so I ordered all the parts, came out to about $460 with shipping and CA sales tax, ordered a few of the parts on amazon since they were cheaper. Only things I'm really worried about is mounting the mobo on the case ( needs washers right? ) and hooking up the HSF, but since it's stock it will just screw right in without any problems right? All stock HSFs have thermal paste stickers too right? Just tear off and slap on?
