Let’s face it, computers aren’t really Buy it For Life purchases. But what better way to celebrate your beloved computer than to give it new purpose? “Reduce, reuse and recycle” isn’t just for plastics!

Our five favorite examples of creative (re)uses for old hardware:

5. Turn your computer case into a grill

Giving a whole new meaning to “my computer’s running hot.”

4. Turn your old-school iMac into a fish tank: The iMac-quarium!

If your old computer has crapped out, you don’t have to send it to swim with the fishes. Let your fish swim in it.

3. A harddrive cotton candy machine!

Props for ingenuity, but we’re not entirely sure this isn’t spinning metal filaments into a fine esophagus-shredding texture.

2. Build Your Own Tesla Turbine

Why? Why not, we say. Even if no one understands what it does, you can say you built your own Tesla Turbine out of spare computer parts. +500 geek cred points.

1. Turn it into cash!

It might not be the most artistic suggestion, but turning old hardware into cash could translate into a lot of fun. If you like taking things apart but don’t think it’s worth putting it back together, you can gut your computer and sell it for parts (or keep the usable parts to build your own custom-built PC).
