Where can I sell my 2006 Mac Pro?

Hi,

I'm new to this forum, so apologies for such a basic question...

I'm trying to sell my 2006 mac pro with snow leopard, does anyone have a good suggestion as to where I can sell it?

I've been told amazon is a good choice, however, on amazon I need the UPC or ASIN, which I don't know/have.

I've bought a new Mac Pro and need to sell my old one to rebalance my bank account!?

The 2006 Mac details are:

v 10.6.3
Processor: 2x2.66 GHz Dual-Core Intel Xeon
Memory: 3 GB 667 MHz DDR2 FB-DIMM

Any advice gratefully received!

I'm in the UK...

Thanks in advance,

Susie

e-Bay or Craig's List are two good choices.
