I think one of the most beautiful computers ever created is the Apple Power Mac G5 (which later just became the Intel Mac Pro tower -- same design, new name). The computer was housed in a sleek, boxy anodized aluminum frame that included standing feet as well as two convenient gripping handles at the top. It was a heavy machine but it was capable of doing a lot. Despite being replaced by a smaller, less expandable Mac Pro, these silver behemoths still work hard today in a number of professional workspaces. I suspect that it will be a few years before these get phased out of the workplace completely.
Anyway, as with all dying tech, there comes a time when people have to decide what to do with a computer that is just no longer able to function. With the Power Mac G5, that came after Apple decided to go full Intel. Nowadays, it's basically unheard of to see software written for PowerPC (and even if you do find it, no modern operating system or accompanying software is written for PowerPC). That means a lot of old aluminum G5's are finding their way onto eBay for dirt cheap. A design trophy, sure, but generally speaking a huge and heavy piece of garbage.
But it's not all bad news. Some people have found some neat ways of re-purposing the old Power Mag G5's. Like turning two of them into a lovely bench, or making a drawer out of it, or turning it into a BBQ pit (probably not recommended).
I have one Power Mac G5. Maybe I should get started on a project with it. I'm just so torn about tearing it apart. It's so beautiful.
