Great for a Mame project - I have two up for sale. Here's the specs:
Intel P4 2.53GHz
512MB Ram
40 GB Hard Drive
Integrated Sound\Video\Lan

Asking $125 shipped anywhere in the 48 contiguous states.
They have some minor scratches, but are in excellent shape otherwise. They are off lease computers from a non smoking business environment. I am writing this on one of them now - they work great. Here is a pic from someone on the net - just to show what they look like:
