Raidmax makes horrible cases - get a Corsair 200R instead. Absolutely no reason to purchase a GTX 260 as it's like a six year old card. What's the max budget? I think I would scrap that whole build and get something different.
ive heard that the motherboard i have selected is not wise for over clocking... and im iffy on the ram. do i need 1333 or is 1600 fine? i plan on over clocking the cpu to 3.8 ghz - 4.0 ghz. would i need a different cooling source? ... this is my first build so trying to learn these things
