If you’re on the lookout for a little side project when you have some spare time, you could always look at modifying a small item such as the humble USB stick. Everyone uses them and having a copper pipe sticking out of a computer looks great.
The article I’ve linked to here shows exactly what to do with high quality photography and a list of materials and necessary tools.
I like that this stick being demonstrated has pipes that stick out. It goes with practicality over the refined look of others and it makes for a refreshing change. The pipes are there to prevent it from rolling away, which is a really good idea.
