I bought this from Ebay and it was already pretty beaten up when I received it.

8 x 2Gb RAM

2 x CPU

2 x 500Gb HDD

1 x HDD Caddy

1 x PSU

The other caddy broke whilst trying to get it out of Bay 0 - this bay may be usable with some judicious bending of a little metal flap that's getting in the way.
