Not only does it look simple, it is very simple to fit a new SATA HD and connect up. No screws, just quick release clips and you're away. I've had *other* makes and models of external HD cases and this one fits the bill perfectly. Ooh yes, the fan hasn't become noisy yet (if it does then it's simple to disconnect). I've also had no issues with transferring files from a few KB to 50 or so GB. Highly recommended!
