The reason we use them is because they are not too expensive, and they have great ventilation, which obviously keeps the drives cooler.

We sometimes get plastic ones in to us for data recovery! Even worst, are the ones that dont come with any ventilation at all.

If you were a Mac fan, they all seem to like LaCie units, however, some of their range have serious overheating problems. We can still recover data from the Lacie units though.
