If you're not good at painting, I'd leave it alone. If you're good at taking things apart so that they go back together, then you could remove the face and other items, mask off the areas you DON'T want paint to go onto (do a good job of that, it's critical) and then work on painting. I'd scuff the surface with some medium to medium-fine grit sandpaper (probably 200-400 grit) and then use a spray on primer that is made for the material you're painting (such as platic and/or metal). Then, once that is dry and cured, start with the color you want it to be. If you want it to be a matt finish, then just spray on a few coats (even, light coats are good, don't go too heavy or you risk having it run on you) until you have solid coverage. Also let that dry and cure according to the instructions on the can. Once it's all done, you can either leave it as is, or go the extra steps to make it a really glossy, high quality finish. That will require having a bit more paint as a base, possibly sanding between coats (very fine grit, wet sanding, cleaning up and then painting more coats) and then laying on the clear-coat. You'll want to sand that as well between coats so that you get a truely glossy finish. This won't be an afternoon project, more like a weekend, or a full week deal. All depending on how good/professional you want the end product to be.
Of course, it wouldn't hurt to get extra paint and practice on something you don't care about first. THAT way, you know if it's something you can handle or not.
