I have built my last two machines and already "rate my build" for this one on Whirlpool.
I have a real good friend who can source parts for me at cost, i generally give him my old gear as his profit.
This is my build thus far. Its a bit of a beast

and i plan to OC as much as i can and get back into some serious gaming.
Still unsure of a decent PSU tho and contemplating a case.
