How much could I sell a Mac Pro PSU and logic board for?

[ValveCantCount]

I have a PSU and logic board from a 2010 Mac Pro. They seem to be going for about 200-250 and ~190 on eBay, respectively. Since I can't verify if the logic board is working, how much could I get away with selling these for?

EDIT: To clarify, this is NOT a macbook pro. this is a mac pro(desktop computer). For some reason there is no tag for mac pro, so it automatically changes it to macbook pro when I try to enter it.

Power brick 10-20 bucks. Board 50 bucks listed AS IS, maybe.

That would be extremely cheap. I see the power supply for this system going for >200 on eBay

I'm mainly talking about the logic board. They are being sold (working) on eBay for ~300 but I don't know how much I could get for one that I can't verify. It may be working perfectly fine, but I don't have a spare CPU lying around that I can put in to check.
