Pimprig has a new review up on Vantec's latest external USB hard drive enclosure named the Nexstar GX. Here is a snip from the review:

"Although it may look like aluminum the enclosure is made primarily of a sturdy gray plastic. The hard drive cage however is aluminum and acts as a very effective passive heat sink. The fins on the bottom of the cage radiate heat to the outside of the enclosure. When mounted properly, the cage fits snuggly on a hard drive insuring good heat transfer."
