World's DENSTIEST A2000 Gaming Rig 

I poured a block to make my own waterblock in my high school metal shop. I too found that I had to go well beyond the stated melting point to not get a porous and nasty pour. I was using mostly fresh copper with a small bit of recycled. Your experience sounds very similar to my own. Killer build, love to see it. 👌🏻

Amazing work, with custom metal casting to boot! You guys are true artisans

Me: They'll never get all that to fit in there. Erick: Hold my S4T while I cast custom copper blocks Sirs you've done it again, fantastic build!

A master craftsman! Incredible how you guys keep on cramming more power into even smaller cases that look absolutely stunning.

Pure inspiration. This is art. I can only dream of reaching your level, but I do dream!

A true artisan you are Erick. And kudos for casting the copper plate yourself. I've only taken an introductory course in metallurgy in my schooling, so I can't say for certain the cause of the low strength of your previous attempts. But, impurities may have been to blame. The introduction of impurities can affect the final crystal structure, which for pure copper is FCC (face centered cubic). The fact that your previous unsuccessful attempts fractured seems to indicate the likelihood of impurities, as pure copper is very ductile. It's also possible that the temperature wasn't high enough. Usually when dealing with alloys, you want to reach a temperature known as the liquidus. This is the temperature beyond the melting point where the metal forms the least amount of crystals and is said to be homogeneous. If it's below the liquidus temperature, then more crystal growth can lead to a weaker crystal structure, resulting in less areas for atoms to slip and therefore causing the part to fail. Raising the temperature could have reached this point, but to what temperature exactly, I'm not sure. Increasing it a couple hundred degrees Celsius sounds like a safe bet. But that's if your smelting furnace can reach those temps. I hope this helps.

I've always wanted to see someone make a CPU-GPU sandwich waterblock. It makes a ton of sense theoretically but compatibility has always held it back.

“That’s Uno.” 😂 Amazing job team. The quality of the work you do blows my mind. Keep it tiny ✊

I have no experience with melting, casting or machining metals except for lead pouring on New Year's Eve. I really enjoyed the ridiculousness of this build.

I was feeling a little bit smug having just slotted a 6 core cpu + RTX A2000 into a ZS-A4DC, to make a small but capable SFF gaming rig. Then I saw this vid. 😮 Daaaamn. That's gorgeous.

I just stumbled upon this guy and found myself unable to think of superlative good enough.The brains,the tech and the eyes. wow.

This is one of the coolest cases I’ve ever seen. Very inspiring that you designed, and manufactured the cold plates and exterior items. Phenomenal work!

That monoblock is just exquisite. Hopefully you could do the same to an actual SFF 3060

There are OEM manufacturers writing notes as they watch this.

I watched the prequel, and I was both amazed and scared. Then I watched the sequel, and I am terrified. The engineering, the creativity, and the attention to detail are just... amazing and beyond anything which I have seen.

Jeez Louise, you guys are insane and fantastic at the same time for pushing small form factor limitations. This is fantastic and incredible. I can't wait to see what you do next.

This is the only truly impressive PC build I've ever seen.

Absolutely unbelievable. People who do projects where the answers aren't on google are the most impressive kind of people.

Wow...just wow. It's nice to see YT streamers do some really custom builds instead of the same saturated, buy parts from store, slap it in some ATX case with store bought AIO's and call it a liquid cooling video. This was pretty awesome!

This design is better than every other mini PC I've seen on the market, no joke. And that's before you consider that it's able to take on a 3060 at almost equal performance. Absolutely mind blowing.

Did you guys check the new RTX 4000 ADA sff workstation gpu announced by nvidia a couple days ago? It comes with 20GB VRAM,DLSS 3,Improved RT cores and rasterization perfomance is estimated to be about an RTX 3070 at just 70W. It is essentially a cut down RTX 4070 ti,pretty cool if you ask me. I'm sure your Copper plate should line up exactly with the 4000 ADA sff as it's exactly the same size of and RTX A2000,could essentially have a PC more powerful than an PS5/XSX at nearly the size of an XSS in this S4T case. Throw in a Shunt mod and overclocking with the new card and i think you could reach RTX 3080(?) levels of perfomance. DLSS3 would also help immensely in demanding games.

I don’t have any experience melting and casting metal but man that’s dope cuz u really made ur own special identintifying piece of computer technology from your own know how to a high degree

There is one thing that could be issue in recycling metal... for jewelry casting you have to use a certain percentage of new metal (casting grain) with the reuse metal whenever you're casting an object. The percentage for silver is suggested to be 70/30 (used/new) I believe. But for copper it may be different. There's also plastic around the copper windings and other contaminates, inside the copper tubing that may have contributed to some issues additionally after casting the ingot Annealing it before working the copper makes it softer and less brittle. Torch it till it glows light red (in a darker room) and dunk in water... The multiple melts burnt off residual contaminates in the metal probably. That's what Ideas I have for you hope it helps

Your dedication to mastering your craft is unmatched- always learning, improving, and striving for excellence. Can’t wait to see what’s next! So very proud of you!!

I dreamt of this build and here it is, my dream is real. thank you for documenting and sharing with us!

im new. when u melted down scraps, then threw it on a cnc, all the different expertise it takes to put this together, absolutely awesome work.

Incredible work! 😮 for casting add anywhere from 5-20% raw material volume overhead (depending on scale). Smaller projects = higher overhead. Then distribute evenly across all dimensions and reduce to desired spec afterwards 👌

I thought that I reached bottom then saw 9 litres builds but you is doing cool in such a small form is beyond my imagination

Super duper clean. Reminds me of when you open up a Mac and all the parts are so satisfyingly fitted together. Would love to see this style of build with more power hungry components

This is pure insanity of the greatest kind.

Not only did you cast your own waterblock fin stack and build a full double-core custom CLC, but through lots of pre-planning you crammed it into the tightest possible package for the hardware involved. Sure it's pointless on a productory level, but as a piece of technical design it's nothing short of art. Great job guys.

Perhaps a regular 5700x would give a lower temp on the CPU than the 5700g? (since it does not have the iGPU in it).

Perhaps copper has a curtain melting point, but the oxides and impurities that form when melting have a much higher melting point. I know it’s a problem when I weld aluminum without scratching off the natural oxide layer that forms in air. Awesome build. Haven’t seen anything quite like it.

Now that’s what I call pure craftsmanship. Also, I am thinking about getting the RTX A2000 for my Dell prebuilt.

Wow that looks amazing. Nice work dude.

Love the video! I've been wanting to see more content on modded turing workstation cards like the a2000 and a4000 but most videos only go over their performance for mining. There's some serious untapped potential for these cards and I love seeing it get explored for their advantages in size and power consumption!

I haven't seen the video yet but by the title I'm thinking SFF Amiga 2000. I somehow don't think that's what I'm getting but that doesn't necessarily mean I'll be disappointed. Lessgoou!

Super awesome build! I would prefer blue over purple, but incredible custom build!

Nice 😎.... This video makes me feel all warm and fuzzy

YES I LOVE IT! THIS IS TRUE PC MODDING LIKE THE GOOD OLD DAYS OF XTREME BUILDS AND OVERCLOCKING!

Absolutely gorgeous work. Love seeing metallurgy involved with recycling copper.

Absolutely outstanding work!

Next level compacting of parts. Recycled custom poured copper. Raw aesthetic sense. Tiny fucking case. This channel is so absolutely *by* SFF makers, *for* SFF makers. It's art. Thank you.

"I made a mistake and had to use neodymium magnets to fix it." This is the most nerdy, 40k solution I've ever heard. And far from the first time I've heard it.

Yet another amazing build 🙌

I realise that I'm late to the party; I've just come across your channel now... However I just wanted to express my admiration for the quality and beauty of this custon cooling solution. This build is pure genius!

If you look real close you can tell they broke several laws of physics.

ive only ever heard horror stories about machining copper. this is insanely impressive

this one forsure has to be the coolest sff builds ive seen

This is freaking AMAZING! Very well done.

Damn. Just damn. Insanely clean and sick!

This is so awesome!! Great job!

An absolutely beautiful engineering work of art

Insane amount of work! The result is magnificent, this is a piece of art.

wtff this is amazing!~ deserves so much more attention

Damn that's cool, hard to believe is sooo close to a modern high tier pc but at 1/10th the size

that is just sick !!!!!!!!!love it

If I had a workshop filled with cnc machines, 3D printers of all material types, and other machines to make circuit boards and forge or cast custom metal parts, I don’t think I’d ever buy watercooling parts ever again. Except for maybe radiators and fittings. It’s so expensive to get all those machines though. I’ve always wanted to make a completely passive custom loop. No fans. No pumps. Just using engineering and physics to move the water around and cool it. Have the entire tiny case be a monoblock, distroplate, radiator, cabling alternative, and enclosure. Disassemble everything to make it as small as possible. Design it so that it attaches to the gpu, cpu, vrm, psu, memory, and chipset, while also connecting directly to the power connectors so there are no or very few cables exposed or used. Design it so that when it starts to heat up that starts to move the fluid, and both the heat and moving fluid cause air to circulate through the enclosure cooling the system.

Love to see the RTX A2000 getting some more attention, given it's immense frame-per-watt. I wanna try my hand at building an efficiency gaming PC one day.

Absolutely amazing! You just made hardcore pcmodders look like amateurs!!

Love the lighting on your cnc beauty shots! :D

Every Build you do turns out even more insane than the Last one! 🤯

Simply amazing. You sparked my interest in SFF again!!

This is absolutely beautiful! Keep up the amazing work and continue to push the boundaries of what is possible. You all are wonderful. 👍

wow that was incredible! a wide variety of skills and knowledge

Im not into sff builds at all, but your content is top notch, love watching it!!

this is illegal you are not meant to be able to fit that much horsepower and cooling into 3 liters. excellent build anyway and i hope i can make something like this someday

To avoid bubbles and other anomalies in copper you have to add a deoxidizer because copper absorbs oxygen and releases it as it cools. Phosphorus is good. Adding a Flux will also not only help the deoxidizer mix but it will also help prevent some oxidation in the first.

absolutely beautiful

almost have to cry its so fkin perfect

You should commercialise this! Great work!

I had absolutely no idea packing a full desktop water cooled loop into a sub 3 liter case was possible

Amazing work man! Just amazing

A cool name for this would be Neutron. A neutron star being incredibly dense, of course.

What an epic build. Absolute top notch, borderline insanity! Wow!

I love the chosen color palette

In terms of liter per fps, gaming laptop still has an edge. I stopped looking at small form-factor pc when I started comparing gaming laptop performance/ liter vs small form factor PC performance per liter. But still, good work!

Nice work. Keep it up! It would be great to see more tiny tech on the market 🤗

I adore the S4T. God-tier little case.

That's amazing. Get these mass produced now!

Seriously a work of art. Ive only built a few SFF systems in real life, but ive built countless in my head lol, this is something i had figured no one had both the skills and the motivation to actually create. Cant believe how tiny you made that custom loop and im amazed at the performance uplift with such a small rad! Great work!!

I wish I had to the skills to do something like this. Heck, I wish I could recreate the last tiny build the did with the A2000.

Generally to get a Clean Pour with Copper you need to heat it up Well above it's Melting Temperature (almost to the melting point of steel... i.e a rapid boil) also, the copper from wiring electric motors &tc. are generally around 97% Pure... because of the coating used to keep the individual strands from shorting out... soon as you burn it off in your foundry you're left with 99.99% Pure Copper.

This was amazing to watch. Such an inspiration and great to see each step and the thinking that went into it. Closest I ever got to modifying anything of mine was when I took a Cooler Master server copper heatsink and fitting it with heatpipes and attaching it to my evga 1060sc with rewired laptop fans to make it essentially a single slot.

This is super cool! I've built watercooled sub-4L systems before myself, but this takes it to a whole new level! After watching this it's confirmed I need more space for tools! haha fantastic work!

Absolutely ridiculous, I love it

This is ridiculous. Amazing job.

Love to see micro-manufacturing and PC building in one video, subbed

This is sooo cool seeing people melt recycling old materials to build pc parts and stuff is awesome work bud

amazing guys amazing.. CASTING your parts fantastic

man that thing is TINY

Looks awesome! Well done ❤

As always, great work Erick! Keep it up

Next time it might be useful to try to slag off any impurities beforehand because if there IS any other scrap metal in the block (like aluminum) you're gonna have a bad time in the future.

Incredible work!

Above and beyond every time

Mind blown. Again!

I can't believe you guys can cram so much power into such tiny cases, I love it, each one of them is a piece of art

It's the most beautiful laundry basket i've ever seen. I love it.

Hope that the radiator and pipe feeds are cooper too
