Query: One of the worst external cases available

I purchased a few of these cases because they were IDE/SATA compatible and metal. However, they are extremely poorly made. It is very difficult to get a disk in the enclosure and once in, you cannot fasten the disk in place, so it flops around inside -- the holes in the case are in the wrong place. What's more, SATA drives only fit upside down (and barely, at that since there's no clearance for the cable so it gets smashed). Definitely NOT a good purchase!
