mobo- $140 (if you know cheeper then this with 4 pci express then let me know)

I wont lie this doesn't seem like the most reliable board. Especially after reading your post that included this:

I bought this board a couple of months ago and it died after a couple of hours. This board is the RMA replacement which I just received.

(Shh! Don't tell Newegg I may have killed it myself.)
