the block is pretty much in-line with the back of the psu - i think its about 15mm distance to the radiator - but i'll measure it at the weekend.
15mm between the block and the rad? I believe the fittings on the EK pump/block are on the top, so if you include the fitting/tubing coming out of the block, is there no space between the block and the rad?
I'll wait to see your pictures.
Also, I would like to know the distance between the side-panel and the 4090 GPU block/GPU PCB, please.
