[foofoo]

i've got a friend who wants to buy an oldish dual proc system that i've had around for a while. it's a
supermicro p6dgu w/ ob u2w scsi
2 x p3 550 mhz slot 1
256 mb pc100 crucial ram
matrox g400 vid w/ digital flatpanel add-on card
intel nic
18gb ibm scsi u2w hd
yamaha 4x4x16 scsi cd-rw
scsi cd
350w ps + case

i dont actually know howmuch something like this is worth. anyone have any ideas?
sorry if this is the wrong forum but it didnt fit any of the others too well. also, if there is a resource that one can use to figure out something like this that someone knows about, please let us know.
thanks

Around 1500 dollars for a very nice system. 2000 tops with a nice air-cooled system coupled with 768mb of ram, 80gig harddisk, radeon 8500. ask more in detail next time.
