To be honest, I was looking to keep radiator costs below 60 - 70 pounds. Also I have the small Hdd unit with a protruding fan module on the back that makes space a little tight what with the pa120.2's depth. Still when the time comes (more that likely mid june) I'll reassess my options.
Im going to be switching the cpu out for a q6600 also going to consider a new motherboard as Im pretty sure this one is a bit borked.
I'll be upgrading the graphics to either dual 2900's or dual 8800gts320s (im getting one through evga's step up program, this is more than likely a problem as I run 1920x1200)
So mid june:
Dual gpu full cover blocks
Quad rad or dual dual rad
dual dcc ultra2 wi' custom top
D'tek Fuzion
mcw30 c/s block
Probably a switech mcres or other cheap reservoir solution
EDIT: just realised I could probably fit 2 of the cora passive solution cores inside the front of my case, that may work better as a dual loop config with the cpu cooled off the cora and a dual rad for the gpus and c/s
