I was looking at external hard drive enclosures a few weeks ago and they tend to all look a like and are just a bit boring.
If you are the do it yourself type that happens to have an extra notebook hard drive and a few dollars lying around for the project you can follow the instructions over at Zonageek and build your own Moleskin notebook external hard drive.
This guy used the Moleskin sketch book for the project which involved carefully (you don’t want blood stains) cutting the pages out to hollow a place for the notebook HDD to sit. Once the pages are glued up, the drive was installed along with the logic board from a cheap external enclosure for USB to SATA and the project was complete and ready to use.
I am guessing the book cover protects it fairly well but the drive could get hot.
Scores very high on the coolness factor.
