rough value?

I built myself a gaming machine and im considering selling it (not on ozzu) then building myself a slightly better one. Roughly how much would you think the following system is worth?

Antec 900 case
7500 W power supply, connectors for 9 sata devices and 4 (6x) pci devices
P5N-T Deluxe nForce 780i sli motherboard, 1333fsb, 775 socket, 4 ddr2 slots, 3x pci-e, 2x pci and 2x pci mini
Q6600(Core 2 quad, 2.4GHz, 1066fsb, 8MB cache)
arctic freezer 7 pro
2x nVidia 9800 GT graphics cards in sli
creative expertMusic 7.1 sound card, with toslink in/out
500 GB, 7200 RPM, 32MB cache HDD
4 GB ddr2 ram, 4x1GB, 800MHz
dvd RW drive
vista home premium X64 OS

this machine will bioshock on full at 200+ fps, call of duty 4 on full at 180 fps average, cs-s on full at 200 fps steady, oblivion varies on full from 80 to 240 fps depending on trees
The cpu's temperatures rarely go above 45C and neither of the gpus go above 50C often at full load

Estimates in £ or $
Try and guess what a large computer retailer would sell this for (I know their specifications rarely meet half of this...)
I am estimating about £1500 ($2220)

I think it will depend quite a bit on the audience. Unfortunately an audience savvy enough to understand the specs is also going to be looking for a deal...

What did you spend to build the machine and how long have you been using it? I think you'll have a hard time justifying selling it for significantly more than you spent to build it.

hmm, built it at the end of november, cost £804

er... don't make useless posts in my threads?
