Power Mac 8600/250 - Whats it worth!?

Looking to sell our old mac (Power Mac 8600/250), heres the spec - http://www.everymac.com/systems/apple/powermac/stats/powermac_8600_250.html

how much do you reckon i can get for it!? I need to place an ad but havent a clue what to advertise it at or what i should expect if i ask for 'offers'!? HELP!

$50 tops

Something similar on mac2sell.net is worth $70 it says. So I'd go for $100 and see what you get. But I'd aim for the antique mac collectors market. Cause they might just be missing that one from their collection and might pay a little more for it. But maybe not as they are a crafty cunning bunch. Anyways it's worth a try.

I'm useing one right now. Upgrade that puppy and keep on truck'en....
