Well this certainly qualifies as my most ambitious build to date. Not sure if Dan intended this, but this is probably the smallest form factor case that can fit the surface area of 4 x 120mm rads while being able to fit a D5 pump.
Why a D5 pump?
The pump/res a carryover part from my previous build and 3 140mm rads should perform as well as 4 x 120mm rad which to me is good enough. It also makes draining/filling much easier (not to mention the pump is quieter than a DDC)
I did have to grind away 2 mounting tabs to reduce the pump height and also drill mounting holes into the front of the frame but it worked out well and the pump was a perfect fit
Parts
CPU: AMD Ryzen 5800X3D + Asus X570I Gaming
Notes: No internal USB C header, so unfortunately I cannot use the front panel connector
GPU: Zotac Trinity RTX 4090 OC + EK-Pro GPU WB Trinity 5090 Rack (Nickel + Inox)
Notes: Single slot waterblock with max 24mm thickness at the G1/4 terminals at the back of the card. Fits nicely with 30mm rads and 25mm fans
The biggest challenge was getting this GPU to fit. There was literally so little space available I had to partially disassemble the case at the rear so I could connect the rear fitting with a (30mm long) tube to the fitting connected to the radiator.The section where the gpu outlets join the radiator is the toughest part to sort out. Once that is done, everything else is far simpler
Pump/Res: EK-XRES 140 Revo D5 RGB PWM combined with a EK-RES X3 - TUBE 110 (64mm) because the default tube was too long to fit
Notes: Unfortunately I think this part has been discontinued, it was carried over from an old build of mine
Fittings: Mostly bitspower 3/8 5/8 fittings with a few Koolance low profile fittings here and there with EKWB ZMT tubing
Rads: EKWB Quantum Surface S280 + S140
PSU: Corsair SF600
Notes: Yes, I am using an SF600 with my rtx 4090. It was a carryover from my previous build. I was prepared to buy an SF750 but before I did, I decided to stress test the SF600 so I overclocked the GPU to 110% power limit, set PBO offset to +30 and ran all fans at 100% then stress tested both the CPU and GPU to 100% (as best as I could, as one component hitting 100% tended to bottleneck the load on the other). Despite seeing sustained power draw in the 570-580W range, for hours on end, the computer ran without a single hitch.
