I'm thinking of selling my desktop cpu. It's a 1.8 dual g5 tower-- 2gb ram, 250 gb hd, most of the bells and whistles. For work I'm finding myself using a laptop all the time. The desktop isn't getting the use it is so capable of delivering on. Where can I sell this thing with ease? How much can I expect to get from it ie. what should I be asking for this machine? Help is greatly appreciated.
