What would ya charge?

Hello all. I’m asking this here because I often see people mentioning that they picked up this software or that hardware at a yard sale. Well, I’m having one tomorrow and need advice.

I have a PII 300mhz Compaq. (Presario I think) 64mb RAM. 8gb HD. 17″ monitor with built-on side speakers. CD-rom. That’s about it.

What in the heck would you charge for something like this? I’ve never even been to a yard sale so I don’t have a clue.

$200??

Thanks for any advice.
