what happened to the evga board you listed earlier? here is a good thing about the evga p55
http://www.overclock...ork-lga775.html
you can use the 775 heatsink so you get more choices
if you end up switching back to the evga board then Id go w/ the megahalem cooler => http://www.prolimate...megahalems.html
OR the TRUE => http://www.thermalri...tb120_revc.html
and here is a socket 1156 if you would rather get than => http://www.thermalri...ooler_1156.html
as for the psu, I'd def get that 850w, it's 100$ at newegg so that's a hell of a deal...well with $30 rebate
and for ram, idk how I can pick that for you hehe your choice, how high are you gonna be oc'ing your cpu?
o and for a SC, I have a one for sale look in the buy/sell sections
