This is the mobo your going to want to buy. Its Z68 so it has onboard GFX, plenty of Phases for your OC, and also has ROG Connect so you can monitor your temps and change your OC remotely while you have no monitor on the box.
Now for the ram. You want it as fast as you can get with reasonable timings, I would go with these...
You are also going to need a cooler. I chose the H100 due to its performance over something like a noctua. Im @ 5Ghz right now folding with temps under 55 C.
Any cheap small PSU will work. Doesnt need to be some top of the line corsair since your only powering a cpu/mobo/hdd
psu $29.99 (one I use for my folding 2600k)
ram $54.99 (also in my folding rig)
