Had to get a 23cm Single Reverse LINKUP PCIe 4.0 Riser cable because the 4090 waterblock is so tall there's no room for slack in the cable and the Double Reverse Riser that comes with the case doesn't work. Can also see the 3D printed reservoir mount here designed by Optimum Tech.
I had to sand down the red part on the LINKUP PCIe riser cable because it was hitting the fans on the radiator. It's about 17mm from the bottom of black connector after sanding. It's just plastic up there so should be safe to do.
Each port of the radiator has the following configuration: Rad -> 14mm rotary offset -> micro 90 adapter -> micro 90 adapter. The 14 mm rotary offset give some flexibility to position the opening near the side panel to line up perfectly with CPU block fittings. This also helps on GPU side to line up with port on the reservoir.
Getting in this radiator was a tight fit. Take off the circled screws on the side and front panels and kind of pop out the side panels on the top. This will give you enough room to sneak it in and then you can pop back in the side panels.
Remove circled screws to help get radiator in.

Push the radiator as far back as you can (up against the plug at the back). This will give you room to get the fittings in and also you can hide some cables in the space at the front.
Fittings: CPU -> 7mm static offset -> micro 90 adapter (on both ports of CPU block). Triple bend to get from CPU to GPU. Very tight! Just barely clears the M.2 stack on the motherboard.
CPU side: Goes under GPU on the outside of power connector.
GPU Side: You can see how it wraps around the GPU power connector. GPU has just a micro 90 adapter on each port.
You can see how the fittings on radiator help line everything up.
2x180 bends. One from radiator to inlet of reservoir. One from outlet of reservoir to GPU.
Acid Green CyroFuel from EK. Really pops with the blue lighting.
CPU -> Rad tube does not prevent inserting PSU fan side out. You just need to be careful to align the top first before pushing in the bottom of PSU. Metal support frame is on one side of tube and power connection is on the other side of tube.
Most of my excess cables are stuffed under the PSU and also up in the radiator compartment where there is some room. Here you can also see the double micro 90 adapters which plug into a 14mm offset above.
How it looks with the side panels on.
Love the tiny antennas! They work great without any noticeable drop in signal strength.
Transparent acrylic side panels from JakefaceCustoms on Etsy. The perfect final touch. Really helps with visibility of the loop and internals. It's satisfying to be able to see my hard work.

Dream PC complete!
It was inspired by Optimum Tech's video with this case and Frillip who proved the 7950X3D/4090 configuration could be done.
It is my second custom watercooled build I have ever done. First one was in a Thermaltake core P3 which is an ATX case with lots of room and only simple single 90 degree bends. So I was definitely challenging myself by trying custom watercooling in such a compact ITX case.
I think it came out beautifully in the end so I couldn't be happier!
