The Innards of My Computer

I decided to open up my computer in order to clean out the dust that had inevitably clogged it up over the course of the last 7 years and what I found was pretty amazing.

A ton of dust, first of all.

I feel like I should have found some rat shit or something.

And then the strangest discovery...

Yeah, a penny. Don't ask me how that got in there. I can understand stuff like that getting into a keyboard or something, but I don't understand how it snuck into my computer.
Best part of all of this is that the computer actually turned on after I put it back together!
