Here is my Dell Optiplex (Small Form Factor)
Condition is not bad.
Its got a Windows XP Sticker with product key
I will have to do a complete wipe, and therefore you will need to install your own Operating System.
Collection from Bradford/Huddersfield. I can package it up if you arrange your own courier.
Its got 128mb RAM in it, and is a Pentium 2.4GHz processor. Works fine with XP and will work fine with Windows 7 if you give it some more RAM.
