Gaming PC - Pricing suggestions?

[ivortheengine123]

I have this computer in my possession:
Asus P4P8x SKT478 ATX
Crucial 512MB DDR 400MHz PC3200 Memory Module W/ Black aluminium heat spreaders
Intel Pentium 4 2.6GHZ 800FSB 512Kb Cache
Sony 16x40 IDE BLACK DVD-ROM Drive - MODDED - Blue activity LED
Panasonic Floppy Drive Black 1.44MB internal - MODDED - Blue activity LED Creative Labs Soundblaster Audigy 2 Soundcard
Maxtor DiamondMax Plus 9 120GBSATA/150 8MB Cache HDD
LG L1715S 17" TFT Monitor
It also has a Radeon 9600 graphics card.
It is an (old style) coolermaster centurion case. It has a Coolermaster Musketeer fan control, and also an aerogate II. I have installed a blowhole in the top with a 120 mm fan attached, and it has an additional fan on the side of the case. The case has been partly modded, but I do not have time to complete the project. The case also has minor scratches which could be buffed out + painted over.
Any ideas on a reasonable price would be appreciated. I am in the UK, but all suggestions would be helpful.
Thanks,
Ivor

You may have a better time parting it out. I would say you have 200 GPB as a whole, but if you sell, you have shipping to deal with.
