due to me finally upgrading to a laptop I have this PC for sale. It is a Dell 745 Ultra Small Form Factor, I've upgraded the processor from what it came with. The spec is as follows:
Intel E6600 Core2Duo 2.4Ghz Processor
80Gb Hard Drive
It has 7 USB slots, ethernet, DVI out (no VGA unfortunately, but you can get adaptors (I might be able to find one at work for you)) and the usual mic and headphone/speaker outs.
I have freshly installed Windows 7 Pro (fully updated and is not hacked or cracked), also AVG Anti-Virus and Office 2007 (this isn't legit and can be removed if you so wish and Open Office installed).
It is a nice, compact unit with only small fans so is nice and quiet in operation, while still having good performance.
The Windows 7 Experience scores are:
Gaming gfx: 3.3
Hard Drive: 5.4
All can be yours for only £60 delivered to your door (the Winnie the Pooh ruler is extra i'm afraid).
