I would build your own. I got an intel MB, 2 gigs of ram, and a Dual Core Processor 5200 I think from Amazon for around 200. I went with the green variety hoping that it would emit less heat. I work on PC's on the side and had an old HP case that I used that seemed to fit perfectly where the coin mechanism was. Here is a pic of mine. I still have a lot of tweaking to do (trim, cover holes etc...). I bought a used cab from a local arcade dealer for 50 rather than spend time building one. Painted the melamine sides (scuff it up, use oil based primer and cabinet paint). All together I have about 500 into this plus time. Another thing I read about and used was a smart power strip. You plug in one device to one of the outlets and when it detects power off it powers down all the other devices. It actually worked too. Now when I turn off the PC the monitor and stereo go off too. I would overbuild/overbuy your PC. They are super cheap now and more power is better than not enough. My Arcade
