Hmm, that's going to be tricky for me, cause my case holds the mobo upside down; the case opens on the right side (looking from front) Lian Li V1100 ...
I don't mean to hijack this but
I think I have my loop imagined how it will work. Now, I am waiting for a few 120mm shrouds, fans, and fan covers. Then, I will be drilling into my case to make things fit and work. I decided to rest the 320rad on top of my case with the openings towards the front. From the CPU block, it will exit out the back to that 120rad before it hits the GPU block, then back to the 320 rad. And after the 320, it goes to the res & pump back to the cpu block
