Barebones PC

Hi all,

I have a barebones pc that I put together a couple of years ago to run Cubase 6.5. I have retired from creating music and wish to sell the pc on to someone who can make good use of it. Any ideas where would be the best place to try and sell it online, other than eBay? I was wondering if there were maybe any specialist websites where people go if they are looking for this type of thing?
