1+ that is a wicked idea you will have a nes that will stomp anything. even most pc's on this forum. measure it out first tho to see if you can fit a mini atx. would be much more pactical. also a volt modded 4850 might be a litle better due to isngle slot. here is another idea tho, you could make a liquid cooling box for your main rig with the nes.
