Pricecheck - Two Alienware systems

A mate of mine is trying to sell these two systems but his not sure what to as for them - anyone got any ideas?

System 1

AMD Athlon 64 X2 4800+
2GB DDR (4x512MB)
164GB 7200RPM
nVidia 7800GTX 512MB
DVD-RW
Genuine Windows XP Pro

System 2

Intel Core 2 Duo Processor E4300
2GB DDR2 (2x1GB)
160GB 7200RPM
ATI Radeon X800XT 256MB
DVD-ROM
Genuine Windows XP Pro

Cheers guys :)

Personally, I'd swap the GFX & optical drives over. Then ask for ~ £100 for the first and £150 for the second?
