the last part of the rig I'm building is the case.
I was suggested the Coolmaster HAF912 ATX, but others have suggested otherwise, that while the HAF912 is a decent budget case, it will be too loud when supporting this set-up and so I was suggested the following 3:
Performance One P280 ATXmd
NZXT Technologies H2 Classic Silent Midtower Chassis CS-NT-H2-W (White)
I am still uncertain which to purchase, and how many extra fans or water cooling will be necessary.
