can you put the xbox processor which is a pentium 3 in a computer. Is just a thought but I was thinking about tring it sometime. Do you think it is possible to do and should I waste my time tring it.

The CPU in the Xbox is just a CuMine Pentium 3 with 128kb of L2 Cache. The form factor probably isn't one available on motherboards so you might as well get a 2nd hand P3 if you really insist on doing some experiments with that chip.
