price to sell for this dual system?

[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 how much 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

If he's really a "friend", give to him cheap like for a hundred bucks or so😀. Otherwise about $1k seems decent.

hey just a little reminder, there are no "price checks" allowed. Even though this is not for sale/trade, the rules state that there will be no price check threads. just a little heads up. sometimes the mods catch these and sometimes they do not.

it's a good point, thanks for the reminder.
i actually am mostly interested in finding out if anyone knows of a good resource for price checking of oldish systems. kind of like a blue book for old pcs. anyone?
