There kind of fun to mess with in a nostagic kind of way. A few years ago, I dug out two old 486-50's from the office basement and took them home to play with. First impression is how fast they boot up and are ready for input. Made me realize how some things modern are not as good as they were. (this was to the dos prompt, by the way)
I ended up painting both computers black and installing them into my telescope observatory shed in the back yard. One ran a dos based freeware skymapping program and the other ran a homebuilt CCD camera that I built to capture images. Fun for awhile but I got tired of the outmoded software and grew away from that hobby as well.
As far as you, if you don't have a use for it, take it apart an marvel at how sturdy they built back then. Then recyle it in the trash. Otherwise, its going to take up space.
Whats the case look like? I've aways wanted to find an old IBM case and mod it to be filled with modern innards.
