I've just taken delivery of an Astro Blast arcade cabinet which I'm going to run with MAME, but the old PC I had to run MAME on won't boot up. Does anyone have an old PC (actually, I just need the motherboard, processor and RAM) available? I've read that something like a 3Ghz Core 2 Duo would be ideal, but I'm no expert on MAME so feel free to comment if you think something less powerful would be OK.
