For how much could I sell my XPS 8100 desktop computer?

I bought it in early 2010 and the specs are as follows:



Intel® Core™ i5-650 processo r(4MB Cache, 3.20GHz)

Memory 6GB Dual Channel DDR3 SDRAM at 1333MHz - 4 DIMMs

Graphics Card GeForce GT430



A sizeable, albeit older, monitor, proper speakers, keyboard and mouse would be included.|||I'll give you a quarter.
