Over a dozen uses for old Macs

I use an old powerpc mac mini with 1GB ram running 10.4.11 as a CVS repository/pserver for my work ... it is small, sits out of the way ... and is more than capable of handling that level of work.

Linux will not run on the Mac Classic. It's right on the front page of the link.
The Mac Classic, with a 68000, has no paging support. On the other hand, somebody might have ported ucLinux to it.... (ucLinux != Linux)

Jokes aside, a key use for old iMacs is to keep them working, if they have a matte screen. If you see the close to 1,000 petitions at http://macmatte.wordpress.com - a common theme is that iMac users, who need matte screens, are having to keep their old iMacs going longer than desired, since, even though these Mac fans want to upgrade, they can't because of the lack of matte screens.

if you have a freegeek nearby, they will recycle or reuse any old computer...

I've got a //c like the one in the picture--tiny green CRT and all--and I meant to do something like this with it

but I never got around to it, so it'll go on eBay... as soon as I can get around to it. :-)

If the old Mac is in working condition or repair is cheap and easy (as was in my case, when I got eMac in perfect condition, just the keyboard and AirPort card were missing ), the best thing one can do to the brave old piece of hardware is to clean it, install proper version of OS (classic, Tiger, Panther) and keep it this way. As a collectible. Or art. Or history. Just like people restore old cars and planes.

What about a Macquarium (IE: an aquarium)?

That's not a mac in the photo... looks like an Apple IIc.

mine isnt too old (700mhx g4 imac) and use it as a kind of server, downloads, printer, appletv, used leopard assist to keep it as current as possible, and use iteleport on my iphone to control it most of the time.
