Opinions on how much to ask for these items

[nothing]

I have here a case that looks like this one, except that it is made out of aluminum, doesn't have the side window and is black:

I also have this power supply

and a 60GB 7200 RPM 8MB buffer hdd, all in very good condition and used for about 8 months. I want to sell that stuff to a friend. How much should I ask for those items?

20 to 40% less then new parts.

I am in the computer industry and I believe that the following would be a fair price, then again, he is a friend.

The case: $20.00 to $25.00
the powersupply: $30.00 to $40.00 (Great PowerSupply)
The HDD: $30.00 to $40.00 (though used)

Basically $80.00 to $105.00 is fair

Hope this helps
