I picked up a $7.99 2.5 inch enclosure and it's sweet. Runs on one USB 1.1 or 2.0 conneection, no extra power connection required.
I also have a "Metal Gear Box" for a 3.5 inch drive that is great since it has a hard aluminum slab shell. It's mechanical sound, dissipates the heat and I like it. But its only USB 2.0.
You requirements are too light.
Planning to DIY sort of stuff for making external hard drive.
Anybody knows which ones are good hard drive enclosures?
Many thanks in advance.
