I've got one freind who wants to sell it to another, she got me to clear it all off and sort it all out, but she has no idea how much to ask him for it..... Bearing in mind they're freinds so they want a fair deal all round, and obviously there's no warranty. So how much would a specced up mac like this be worth (im in the UK, so and $ ill convert them using a currency converter) - I've really got no idea. Specs: Intel Quad core 2.8 xeon processor 6GB RAM DVDRW 1.8TB RAID0 (3 disk) 650GB Main HD One of the RAID drives does need attention or replacing though. Any price suggestions for something like that?
