I've used the Supermicro enclosures that turn 3x 5.25 bays into 5 3.5" bays and been pretty happy with them. Something similar to the CSE-M35S. More recently (5 years ago now :-) I tried some 5 bay E-SATA enclosures so I wouldn't have to pack these Supermicro into the chassis, and the eSATA were nothing but trouble. Hopefully better these days.
