The coincidental timing of this video and Linus' pool PC is almost comedic.

That. looks. incredible.

As a licensed plumber, I've always wanted to build a PC with a water cooled system integrated with a homes potable water plumbing system. We could build a loop in the homes cold water system and use a recirculation pump to displace the heat of the PC among the entire plumbing system 👀 I guarantee it would work

4 Months without a video? This guy must be water cooling his whole house by now!

Hello, plumber here! Note on the soldering of the outer piping: you used the wring kind of joints. These have a rubber inside of them, which won’t take kindly to tho soldering process. I’m sure you’ll fare much better with joints that are meant to be soldered with. Some tips if you’re interested: -ensure enough ventilation -Make sure theres no dirt on the pipes -make sure to use sandpaper on the bits that will be soldered -after that use some flux (s-39 will do great) to cover the surfaces that are to be soldered. -after assembly, make sure you heat both parts about equally -the tip of you flame is the hottest -if the joints are at the correct temperature, the solder will be pulled in the joint. Just touch one spot, the flux will pull it in. Stop when you can see solder all around the pipe. I always leave a little droplet underneath (assuming your weld is horizontal) as proof that it’s full. -i know it sounds obvious, but do not any part of the project with your hands when heated. It’s all hot

I love not only how it looks, but also how this setup is 100% silent and 100% dust free

When your mom tells you to go play outside.

This is beyond cool, and the temps achieved were impressive. But I was more impressed by the underwater footage of your pond and the fact it was actually 7 feet deep!

Another great way to prevent a leak would be to have the inside be pressurized slightly. If there is a leak, you will have air leaking out instead of water leaking in, and you can have a pressure sensor that warns if the pressure is going too low

My man, you have aerial drone footage, submersible drone footage, footage from a submersible vessel that is not a vehicle but a complete personal computer with visual feedback temperature instrumentation, plus footage from whatever other gear you have for the tutorial build. The commitment here is mind-boggling. Absolutely and imminently professional. AND the build quality is insane. Bravo.

I think this would make a lot more sense with copper gaskets, and an electrically neutral medium or an electrically neutral coating to prevent corrosion, and a positive interior pressure which would help reduce buoyancy and a sealed top so if there is a leak, the natural buoyancy of the system will prevent liquid from entering. Beyond that, this is genuinely incredibly cool. When its got the yellow and dark blue lights going (yellow rim, blue interior) it has a weird aesthetic resembling some of the real quantum computers I've managed to see. Quite surreal.

17:45 Just imagining it continuing to go down as the foam slips off and the frantic attempt to catch it from going fully underwater

Copper itself is a biocide, if you plan to keep it in the pond you could consider to apply a coat of clear varnish on top of it. That may reduce the thermal conductivity though

18:35 If only someone had built an ultra bright screen for outdoor use🤔. Amazing video and impressive design as always Matt.

Looking this guy build stuff and looking at how happy he is doing it gives me years of life man

Way to go! This was so intriguing to watch. Thank you for all you do, Matt! Your quality of work and video production is smooth. Always has been. :) Cheers!

I work for a heat pump manufacturer, and your solder joints look better than most of the joints I see being produced here. Great job.

Funny that you and LTT both released watercooled PCs that both use radical forms of watercooling, yet both are so different. This PC looks amazing! Great work!

This is legit the coolest thing I have seen all year.

It might be interesting to fill the inside with Mineral Oil, that way, because Mineral Oil, Acrylic, and Water all have similar refractive indices, you wouldn't be able to see any of the protective bits, and it would just look like the electronic hardware was submerged directly.

The fact that Linus, you and basically homeless all uploaded crazy pc builds today is just phenomenal, thank you

One mistake in the video: at around 14:42 you mention that you don't see any bubbles coming out of the enclosure so it must not be leaking. However you would never see bubbles with a setup like this, even if it was leaking. Because the pipe on top already provides a way for the air to be displaced/escape and water to get into the enclosure. This basically means there is no need for air to get out of the enclosure where the leak is, for water to replace it.

I wonder if the companies who are making those large scale underwater servers have thought of combining the heat of the system and the cold of the water with a Stirling generator (which generates electricity based on the difference of heat on either side). Would be a neat way of local power generation to increase efficiency

You never cease to amaze me! This build is incredible! I'm not someone who works in the professional field but this is beyond even that. Your videos always brings inspiration for me to try new things. Awesome job!

Can you re-do this video during winter? Would be awesome to see this performance in extremely cold water!

Just my 2 Cents. You could add a hygrometer and dehumidifier packs. If you closed up the PC in 24°C with 50% Air Humidity, you'll get condensation at around 12°C. Meaning you will have water inside at Fall and Winter. Also you could add a way to increase the Air Pressure inside the capsule, like 1.2 bars. That will help against water ingress.

Amazing piece of work.. thank you very much!

I dont know why but the most fun for me is too see how happy you are because of this and how much fun it is for You

The pre-soldered copper fittings were a great choice just for style alone with those ribs. Very steampunk! Yet another amazing build, Matt.

Every diy perks video is better than the last. You can really tell he's putting a lot of effort in to make the best possible videos

always wondered about this idea, nice video

I so love this channel. Being completely hamfisted when it comes to doing anything, (except building PC's), I congratulate your invention and ability. Great stuff!

you should remove the moisture inside the case to avoid water droplets forming while immediate cooling

Man! Asus' sponsoring you now too!? Im so happy for this guy, you've really made it! I still remember watching a video of you way back 2015 just because I wanted to make my own photography lights. I've been hooked to your channel ever since then! 😂

DUDE! That is EPIC. True talent, skills, and experience beyond normal levels.

Well done sir! I've always wanted to try this but haven't yet. The design you came up with looks amazing and is quite functional. Superb video! Thank you

I am BLOWN away that you didnt test it'd be waterproof first without 5K$ worth of components in it first!!! you're insane in the best way possible. Love it!!

This guy is so watchable. He should have a TV Show with a bigger team & the possibilities would be endless.

Absolutely insane, doing this is always one of my dreams but i never took actions. Keep up the great work!

Really liked the video.. even though it seems weird but appealing.. great efforts you take for video making.. tysm

I saw linus' video where he cools his server using his pool and now this. Also, the shot at 15:38 where the PC turns on is weirdly haunting. The metal pipes evoking steampunk vibes, the mercy water in serenity and then suddenly this industrial device steering to life, disturbing the quite with it's magnetic sound. Very cool. Also the pond shots were amazing.

I don't understand why LMG hasn't flown out Matt by now, he's literally THE guy for innovative pc design and execution! Awesome work as always sir, fun to see the steampunk aesthetic return in this video :)

This is one of the coolist thing iv ever seen Great job man!

I love this guy always keep the curiosity there and make real good use of people's wonders

You never fail to amaze me. :) A tip from a blacksmith and machinist: If you put a wet rag around solder joints that are close to the thing you want to solder, it won't de-solder and cause a mess of running solder. The recipe for a good solder joint is to clean everything thoroughly as in "A surgeon could operate on the surfaces" clean, then apply flux. Apply heat to the two materials taking into account that the larger piece will draw a lot of heat away. Then carefully "probe" the material with the solder to see if the temperature is hot enough...proceed to solder by letting the solder "wick" into the joint. Work the flame around and let it do the job of soldering your joint fully. Clean...and enjoy your work. ;)

Apart from your amazing technical skills, I have always viewed this channel almost as an art channel, since there are few "technical DIY" channels who create such aesthetic builds and videos, but this was on a new level entirely. I am not sure, but I guess there would be many people that would pay unhinged amounts of money to have a pc like that, maybe turn this into a product ;) (among those people, possibly myself included...)

Just randomly stumbled across your channel this morning! Your content is quite entertaining!

This brought a smile on my face! This PC looks absolutely stunning and OMG it works flawlessly!

This looks like a miniature version of the quantum computers they use now. Absolutely stunning.

Maybe you should add a umidity sensor inside, as you can calculate condensation on the acrilic walls, and a cap on the top tube for blocking the rain

This is by far the MOST unique and amazing pc build I’ve ever seen!

you are my favorite channel ever. You inspire me SOOOO much to do the things I love to do, and you make me know that anything is possible, and most importantly for me, it dose not have to be productive in order for me to do it. You have taught me that if I want to do it, then I should do it, no matter if it "helps my carrier" or "makes money". I dont usually comment on alot of videos, I just want to say thank you for being an inspiration to me and many others who think the same!

Dude, I am so happy for you. In every video we see how much of a blast you're having. I never, ever feel myself wondering "why" for a certain project. You give off the most wholesome "why not?" vibes and its infectious.

Love the steampunk aesthetic of the copper and "crystal" (aka acrylic) parts, such a beautiful build. And I'm also seriously in love with the laptop, what a fantastic pair of machines they are! Keep up the Perks! Oh and PS: You could alway have put a tube down the main cable entry, filled it with sealant, and added a small aquarium air pump to maintain positive pressure within the chamber, that way leaks would have been evident by bubbles but being positive pressure inside the components wouldn't have been at risk.

That's amazing. Bravo!

This looks beautiful! Copper is such a nice looking metal!

i've noticed that the cooling design resembels the one of the nuclear reactor, where there are two indipendet cooling loops. one in direct contact with the uranium rods which makes the water radioaktice and on the outside a loop with normal water, which turns the turbines and stays clan. thats very neat that you implimentet this in your design!

Matt, please never change. Your attitude and enthusiasm makes me so happy. Your projects are amazing!

This is Fabulously Fantastic. Stuff like this would make anyone want to learn about PC's

Awesome video and idea!!! Great job!

Having seen this video i am now building a dam inside my apartment. The downstairs neighbours arent that happy about having an entire room filled with water above them, but hey, gotta chase those FPS! Thank you DIY perks!

Uses a Seasonic power supply....I sea you

That's absolutely beautiful piece of art!

This video was insane good work!

Would have loved a shot of the underwater PC at night, lighting up the pond. Amazing work as usual.

Imagine connecting a Controller to it... That's a Billion-Dollar Idea!

I remember watching you when you first started, building simple things and fixing televisions... you have upgraded, my friend 😂. Ive been away for years and come back to this account and i still find you even more enjoyable! Its amazing you have upgraded!

this is a work of art. absolutely incredible

It just warms my heart that you're enabling tons of people to touch grass without leaving their PC's behind

Great build! If you plan to keep using this pc, I suggest pressurizing the inside a bit higher so that if a leak forms, air will go out before water goes in, plus the pressure falling gives you an early leak warning!

I almost cried looking at this build. It’s so beautiful 😭

So data centres are now heating our oceans, what could go wrong?

Crazy that this video and the LTT pool water cooling released on the same day! This really seems like it could be a cool way to save power on heating/cooling at an industrial scale.

This coming out the same day as Linus's is hilarious

You are my new favourite UKpostsr. Could literally listen to you talk all day long ❤❤❤

I love how excited he looks just to make and test it :D

I amazed how well you engineer everything while keeping it stylish.

Matt would be such an EPIC Physics teacher. Excellent engineering and a magnificent build - keep it up!!

Wow the cooling is great

A Classical Quantum computer in your Pond, that is marvelous research

Probably could have done an air vacuum test to check sealant. Would have been funny if you used blue lights so it would look like a reactor! 😄

There is a simple little water leak detector that's made for going under water heaters or in basements and cellers. You could install one at the bottom to get an instant audible alert on the first sign of leakage. Moreover, if you wanted to be really fancy... take that same alert signal run it thru an arduino or similar programable logic controller that triggers your pulley system to pull the computer out of the water.

Not only did it work but the build looks awesome!

an under water pc was made before gta6💀

Just a suggestion. I would put some kind of water proof barrier on the top where the cables come through. I can just imagine a medium sized bird or a stick landing on this and it’s curtains. Awesome video as always!

IMO, this was one of the most unique and artistic hardware pieces you have built.

This so great . Good job on photo shop

Great video and interesting idea as usually. I wonder what the temps would be when you keep it outside the pool for a couple dozens of minutes.

you have broken the record with this, I am blown away with your skills, creativity and most of all friendly and wholesome style in presenting your projects, good luck to you, love to see your next awesome project!

The ultimate touch grass or literally touch WATER PC. Perfection and unironically seriously an amazing achievement with what looks like a greatly satisfying design!

This is insane. Like something you'd see in the lab of a video game scientist

It's an impressive build, I would have kept it on my desk just for the looks, is amazing and so unique

12:08 Bro has a complete ocean in his backyard 💀

the reason why your joints might look a little messy is because you're using pro press fittings instead of solder fittings. those little rings you see on the 90's are supposed to have a rubber ring inside, and they are meant to be fully compressed into the sides of the pipe using a pro press. if you'd used normal 90's, im sure the end result would have been much easier to get and wouldve looked much nicer!

Glad this is being explored more, Navy has been using a similar technique for a long time now.

hands down coolest pc ever good job mate

14:28: *Chernobyl engineers after setting up the reactor*

If you wanted to get rid of the metal pellets, an additional steel plate to act as a bottom to protect the bottom of the copper pipes might be a good way to do it.

Man it was so sick project you have worked on!! I am an engineer myself, loved the way you assembled it and the accuracy ofcourse...keep working dude STAY HARD ❤

Geniusly classy as always❤❤
