So, all the builds the OP has been suggested look good and compatible.
Dual core, quad core, unlocked Sandy or Ivy Bridge. 7850, 7950, 670. SSD and/or HDD.
All good stuff.
I can`t help but think a i3 2120, H77, 7850, SSD, HDD. At one time the OP needed a monitor too.
Whatever you guys come up with just get this thing ordered and built already.
