I don't want one of these modified HDD cases from Meninos, but the pop art work does look quite cool (read: acceptable for the office only).
Their branding is also very interesting. It looks like they were designed to appeal to geeks, judging by the choice of covers they offer, such as the Star Wars one!
I guess if you spend all day at your computer, it may be quite nice to pimp out your hard drive. Surely you would get bored after a while, the HDD would go back on the floor, and the only difference would be that an expensive HDD cover is also getting covered in crap from the floor.
