Hi, Im about to move into a new case, Lian LI PC-D8000, atm im planning on moving the current hardware to it which is SUPERMICRO X9SCM-F Intel Xeon E3-1230 Kingston 4GB ECC DDR3 1333 2x IBM M1015 8x Hitachi 5K3000 2TB (5400rpm) 8x Seagate ST4000DM000 4TB (5900rpm) 6x Samsung 1.5TB (5400rpm) I'll be swaping the 6 samsung for 6x WD 5tb reds when they hit the market, but not planning on changing toward 7200rpms drives ever. When 4k movies become mainstream, im planning on modding the case to fit 32 to 36hdds (will depend on how the modding go). Still undecided on which PSU should i upgrade to, thinking on todays requirements, according to the 2amp rule on the the first post, the 24x2 = 48amps, in the future 32x2 = 64amps, an 850W with single 12V rail will have 70amps, so a little tight for the future, but also not all hdds take 2amps fully, some go lower, so i was thinking 850W would be fine. I am considering the Corsair RM Series 850 Watt ATX/EPS 80PLUS Gold-Certified Power Supply - CP-9020056-NA RM850, but open to any suggestions that could fit the needs better.
