Mini Wii Console Shaped USB 2.0 2.5" SATA Portable Hard Drive Enclosure - White

Pros: Compatible with wii - using gxloader or other homebrew loader
Small, very compact
Uses standard miniusb cable, not that a-a nonsense, so many others use.

Cons: Build quality is decent enough, espec. if permanently connected to a Wii or wotnot... but for travelling purposes, I would choose an aluminium case, which is typically cheaper as well
The case has no dimensions, that actually fit the wii. It only looks like a miniture wii... If it was as long, as the Wii is wide, it would look nicer...

Other: Great, if you have a wii, as not all externals are compatible.
Too expensive, if for any other purpose.

Pros: Easy to install the Hard-drive in 1. Pop it out of the packaging 2. Unscrew the phillips (plus/star) screw 3. Open case 4. Clip the 2.5" Hard-drive in 5. Put the cover back on 6. Screw back on the screw 7. Plug the included USB cable in 8. Plug into the USB port on the Computer 9. Set up the Hard-drive 10. Ready to go And also comes with 2 whistle key chains that looks like the controllers, a case to carry it in.

Cons: none really

Other: I would get if you want to make it look like there is a mini Wii
