Well , I got it in today ! Whoo hoo ! Im so excited !
The motherboard is an asus M2R32-MVP crossfire ready motherboard , AM2 socket.
The processor is an AMD Athlon 64 X2 4200 (65w) dual core (AM2 socket)
Im planning on moving it into a new case , with my old sata HD , 1 gb 533
ram , x1900 GTO , sound card , etc.
Only thing is... a friend told me I need a new OS. With my dell dimension 4700 , it had a feature that allowed me to make a cd copy of windows for installation. Do I really have to reformat my drive and if I do , will my cd work? I have an unopened copy of windows ME around my house somewhere , but I would prefer to keep XP.
I have the manual for connections and everything , but was just looking for a walkthrough on getting it up and going. Thank you !

(I have a lot of my first semester college coursework saved on my HDD , so the issue on whether I need to reformat or not is an important one O.o')
