What do you do with a PSX/PSOne when you have a working PS2?

Now that I have a PS2 I'm thinking I'm either going to put my PS1 away and let it just sit there forever, or I'll sell it.

Chances are, I'll keep it-- knowing me, if I sell it I'll come up with some crazy reason that it was a bad idea in around a year.

I have mine, gonna mod chip it and put it in a clear case. It deserves a clear case, maybe some LEDs.

If it's the little PSOne, get a screen for it, it's awesome. If you have a first generation PSX and a nice sound system, hook it up and use it as an audio CD player (seriously.) If it's neither of those...into the closet it goes.
