It has a motherboard etc in it and I think it's running Windows95, but I can't really remember the precise details. I could hook up a keyboard, mouse and screen to confirm the spec if anyone is seriously interested.

As per my other posts, these are free to a good home or you can throw in a bottle of decent wine if you're feeling generous!

I'd just like to save them from landfill really.
