You will need to buy Windows also. The Windows on your existing HP can't be transferred, assuming it came with the HP.
I'd probably install Linux, and switch to Windows when I have the money.

If you do that, you may be able to get an Intel i3 CPU, which might be a better all-around idea.
I dont know yet, maybe I'll go for an AMD cpu, or otherwise an i5. (If it fits with the mobo)

Thanks for now, and I'll see what I can get.
