so i'm trying to build a nas i have a 4670k from another failed build, i've seen some posts on here saying all they use for there nas is a combo cpu/mobo or evan interated with 4 or 8gb of ram, so i'm wondering if it would be better to underclock the 4670k to 2 cores and get a mini itx or save some money and get a intergrated cpu. this is just going to be used as a file server just stoaring some important files and backups...i would be suing unraid for this with some nice and expensive (lol) 7200rpm 80gb drives..
