So long as the laptop is not using a desktop CPU in it, right

About enclosures, the main reason for them used to be the longer warranty with individual drives as opposed to the much shorter 1yr one with the all-in-ones. Tho i think the mybook's have a 3 yr one now.

A good enclosure is always the best choice, prob is the ones sold here are not that good quality, if you look in the west there are new ones coming out every 6 months, the chinese just keep pumping them out at a crazy rate.

Then there is the question of interface, firewire, USB or eSata.

eSata is the best as it functions just like an internal drive. Firewire if you have the interface and lastly USB which is what most have with pc's.

Personally i've just got bigger drives for the desktop instead of bothering with enclosures, too much bloody effort to find the right one
