If you guys could help me out id appreciate it

Wish list showed up as empty.
I believe my friend has an Athlon II x2 3.1 GHZ, 4 GB DDR3 or DDR2 (Ill call him and ask right now) , motherboard unknown (probably asus or foxconn, its a standard dell mobo) 500gb sata 3gb/s drive no ssd, standard dell case and power supply @ 250w

EDIT: I'm pretty sure its AM3, but if its not and the processor is upgraded we can get a free mobo from microcenter
