Cutting ones losses

I was planning for months now to build my rev 3.0 computer (The infamous DDR SOYO of a few posts ago) and take the old system, and make it into my set top DVD box. However MS has linked us to that little FlaxATX gem, and I have decided to (possibly) scrap the plans of using this full fledged system as a set top box and instead wish to grab an AMD based FlexATX system. This brings up a notion to me. Why not (gasp) sell this old box, and make a little ching in the process. So, without any further ado I ask you, how much could I expect to get for the following system:

ASUS A7V(non 133)
1Ghz T-Bird
256 megs of PC133
Either a GF 256 32 meg DDR or a Radeon 64meg DDR (haven't decided yet)
20 gig ATA66 WD 7200 RPM HDD or 30 gig ATA66 Maxtor (yet again I can't decide)
SB Live! MP3
PC tel junk modem (not that I'll tell the buyer "junk")
50X CD ROM drive
All stufed into a desktop case

Note: A close friend of mine recently paid $600 for a system based on the following:
Alienware (yippy)
PIII@733
128 megs of PC100 (yeah PC 100 cause the mobo doesn't a support 133Mhz memory speed, how dumb)
GF 256 32 meg DDR
15 gig Seagate I believe HDD not sure of the RPM
Addtronice mid tower
SB Live value
Cambrige audio 5 piece sound system 4 sats 1 sub(the cheapest 5 piece they make)
