What brands are all the parts? Cheap-O brands are going to bring less.

By "custom", do you mean it's got a window kit, cold cathode, fan bus, etc . . . ?

be more detailed.

how fast and what brand cd/dvd drives?
what mobo?
what socket cpu is it 478 or the other?
what speed ram and what brand?
what sound card?
what psu?
what do you mean by GF4 ultra?
and how old is the system?

based on what I know of it now I'd say $300-$450, if its in good condition and has the parts I think it does.
