I'll give you $40 for the 40gb drive and the stick of 128mb ram.
My PC is almost twice what that is and I'd be lucky to get $200 out of it. I've learned you have to cut your losses when selling something if its that old. If I were to try to get the $800 or so that I put into this years ago people would crap my thread and flame me to no end. Good luck there buddy.....
