Ok, so as I'm buying parts for my build I was also thinking of selling some old stuff (probably 0 value, but might as well try at least).
The parts are these ones:
Nvidia GeForce4 MX 4000
Intel Pentium 4 2.02GHz
Case (don't know model, I think it's ASUS? :P)
And an ASUS GeForce EN8500GT (completly new, haven't used it)
