Custom built Gaming Pc, HELP HELP HELP!?

+1 for last post but I have to add something.Swap that cm 690 with a cm 690 2 or a cm storm scout,haf 22,haf 32 and similar.These cases have an opening for cooler backplate installation and will make your life easier.Believe me ,I have the cm 690 and I wish I had gotten those.Now as for the ram,instead of the dominators get some g.skill ripjaws which are prettymuch the same and have a lower price.Finally,even though I haven't checked prices(so take this with a grain of salt) I would recommend one of msi's or asus motherboards with a lucid hydra chip.It should come in handy and is worth having at that budget.You don't need a network card or sound card.The embedded on the motherboard will be enough.As for how long this setup will last you..A rough guess is:for everything on high resolutions and maximum detail 1-2 years,for everything playable but not necessarily on max 5-10 years.
