I think I've decided to sell my desktop and buy a laptop instead. The PS3 has taken over all my gaming needs now so this is just overkill for iTunes and the internet.
The components below need pricing up so I can see what I can raise for the laptop:
Intel Q6600 G0 OEM
Gigabyte GA-G33M-DS2R uATX
4Gb (2x2Gb) Corsair DDR2 6400 DHX
320Gb Maxtor SATA
160Gb Maxtor SATA
160 Samsung Spinpoint SATA
Inno3D 512mb 8800GT
Enermax 535w, 38a
Silverstone TJ08B
22" Samsung SM225BW
All but the monitor, HDDs and case are boxed with all the bits and pieces. All are within warranty with receipts.
