I've tinkered with cheap nas cases. It's easy to end up with a case that: so thin/flimsy that it rattles, crappy plastic carriers that seem designed for 3 insert/removals before dying, terrible airflow, and/or loud. There are exceptions of course, but it's not an easy task to find a nice solution that is quiet, vibration damped (easier on spinning disks), good airflow (keep drives cool), nice mini-itx or similar motherboard (ideally with ECC), an expansion port (10G or M.2/U2 cache), etc. One I've had my eye on is the Fractal Design Node 304.
