Add a second internal hard drive to your laptop
 

Like any geek, I have a ton of old drives. They are mostly used in external cases for backups or to run a VM on to do some work that I don't need on all the time.

The other day, I was digging through a drawer and I came across a 100GB PATA notebook drive that I had replaced in my personal laptop with a 100GB 7200RPM. I pondered the thought of putting it into an external case so I could do some Ubuntu package deployment testing when I realized it would be really very cool if I could make the drive fit IN the laptop.

So, I pulled the notebook apart and began walking through hacking my spare drive into it.
