Coolermaster Chassis What Is The Value Of This Home Built System?

What is the value of this home built system? - coolermaster chassis

I do not need the former office tower, now that I have a laptop, but not a model that really mark a frame of reference value. I know that it is outdated in several areas, very much. What do you think can succeed? Here are the specifications:

Seagate Barracuda 250GB HD
1 GB of RAM (two sticks of 512 MB)
Gigabyte GA-8IPE-1000-G with onboard sound
Intel Pentium 4 2.63GHz
5 USB ports on the front and rear, a front audio connector
Sony DVD-RW/floppy
Nvidia GeForce FX 5200
Service Pack 3 of Windows XP Home OEM with original disk
Great Coolermaster chassis black with excellent movement and 2 or 3 cages of the unit is still available.

Thank you!
