Took one of these in PX for an old recon PC i put together.

Popped in a new PSU and it works fine. It's the HP Slimline s3200n version with Athlon 64 4800 cpu, Nvidia 6150 on board, wifi built in, a card reader and 1 gb ram.
Perfect for a small media centre and quiet as a mouse.
Bloody bargain actually.
