It depends on how you mean "painting on the computer." If you want to paint pictures using the computer, you can use GIMP (which is free), Microsoft Paint (comes with Windows), Paint Shop Pro, Photoshop Elements, Photoshop, just a lot of things. If you want to paint the computer itself--gamers who go to network-gaming parties would want to do this, and it'd look cool on a laptop--start by taking the case off. If it's a plastic case, use two coats of Rustoleum Paint for Plastic to keep the paint from eating the computer--after which you can use any kind of paint on top of the Rustoleum. For a metal case, prime it with automotive primer then paint it with any paint you like. Let it dry for a day, clearcoat it for protection, let THAT dry for a day and put the case back on.
It would not be advisable to use any paint on a keyboard in case it gets into the mechanics.
case he like 2 paint
The case is not normally considered computer hardware. However it is "hardware" in the same sense things that you buy in a Hardware Store are hardware (e.g. sheet metal, angle brackets, screws, washers, nuts, nails, plastic, paint).
extra fine sand paper should do fine
A case protects a computer when it is dropped.
If it's USB 2.0 it is likely the faster one. You could also guess and check but most manuals for either your motherboard or case will tell you what each of the USB ports are capable of.

something that case computer is vials i think
Your original exit plan may be engulfed in flames.
I'll assume you mean "matte paint", in which case it is simply a paint which isn't reflective and has no sheen (ie. it isn't shiny) to it.
