Pros: Reasonably well built.
Cons: Sas? Well, the connector *looks* compatible, but all the sas drives I have seen are (apparently) thicker than the allowable 12.5mm. That is what I get for eyeballing it. I have a small pile of old server sas drives that I was going to use in two of these, but guess not. Best i can tell, the enterprise server class drives are 15mm.
Overall Review: The drive trays a bit delicate. I dont think this is a problem for me, but some people can be... a bit hard on items and may break these.
