Hi everyone. This is my second build, and my first try at water cooling. Oh, and yeah first wall build too I guess.

Started with a 30"x40" 3/16" sheet of aluminum, built a wood frame with some 2" standoffs, and spent time cutting, drilling, measuring, and sanding based on my cardboard mock-up. Once I was fairly confident all cuts and holes were in place, off it went to Powder Pro in New Bedford, MA (best you'll find, if you're in the area).

Once back, component assembly was next; motherboard (Taichi Lite), Bykski D5/reservoir combos, and the Corsair GPU block are all mounted on standoffs. The Bykski 40mm rads are screwed flush from the rear. Tubing took me a while, learning the tolerances of the14mm acrylic, but I did enjoy it despite several flubbed attempts! I went with a blue/red theme for the two loops, sort of a vein/artery type of thought, for lack of any better ideas at the time. Fittings are Barrow; the triple O-ring design inside their compression fittings really inspires confidence. Bought most of the fittings and tubing on AliExpress to save money, along with the Bykski components. Coolant is distilled water with biocide and Mayhems dye (great people to talk to! - Amazon sent a bottle of dye from 2018 so I was curious, as were they, to see if it held up. It did great) As you'll see, not all angles, bends, etc. are perfect. I'll admit I kinda rushed to get it finished and running once I finally got my hands on an MSRP 4090FE from Nvidia's site. Not sure if I'm a fan of RGB, but the Cosmiq daisy-chain fans were a must for cable minimization and came with it, so...I'm enjoying the light show for now.

Only one issue since I've had it up and running for a couple of weeks: one of the Bykski pump/res combo units decided to start leaking when water temps hit 30C. It passed air testing and no leaks at lower temps; maybe tolerances loosened up some when it got warm. Ordering the pumps from overseas bit me on the ass a bit on this one, but it all worked out eventually.

I had hoped to get a motherboard with back connectors to really minimize visible cabling, but it didn't seem the time was right for what was currently available. The power supply, Quadro controller, and hubs are on the backside to hide as much as possible.

Overall I am loving a wall build, I just don't see the upside to cramming everything into a box where you can't see and enjoy your components. It's also MUCH cleaner and easier to work on! And yes, I know my AIDA64 sensor panel is huge, but I wanted easy access to temps, etc. while I dialed in my fan and pump curves with Aquasuite. Still, I might keep it there, because I'm old and it's easy to see what I need to at a glance!

Thanks for checking it out, and any constructive criticism is welcome!!
