I am selling my old PC to work colleague and I'm not very good with pricing older components, just wondering if anyone could give me some advice on a fair price

System:
CPU: core2duo E7500 2.93ghz
Motherboard: Asus (forgot which)
GPU: Ati 5770 1gb
Memory: 4gb (generic memory)
PSU: generic PSU 450w I think
HDD: Western Digital Blue 500gb
DVD Drive
Windows 7 32bit
Black PC case.

Thank You

£100 - £120 is my guess ?

thank you for the Stealth,
As its a work friend ill do it about the £100 mark.

Yeah £100 - £120 seems like a fair price for a machine like that.

I paid £80 for one for work, second hand, with a 1440*900 monitor, 2.4 ghz single core CPU, windows vista (or 7), with ram in and keyboard, hdd etc, just off shpock.
