Hi, i am new here , currently i am doing research on building small gpu farm for folding, my specification would be using 4 x ati 5970 + water cooling and a quad pcie x16 mobo, the problem is i am not generally water cooling kind of guy, normally i preferred my cooling solution into air, so i would need advice for those who experienced building something like this, what would be the best affordable mobo for quad pcie x16? in term of performance and reliability because i planned to run it for 24/7 for the whole 6 months or a year, the platform(lga 775, 1366,amd) would be not really matter, i am only on too opencl performance by using these setup. And about the water cooling solution the question would be the same, what would be the best, affordable, easy to install? also which case do will be enough for this baby & it's coolant army? i am not looking good fancy housing only for fits not for display. Is there any tips,tricks,critiques on how running quad ati for optimal cooling and 4 x water cooler placement? , do i need 4 x pci-e x16 extender to get the better card placement?. And is there any review about general temperature outcome on running this kind of system?
