Yeah, that's in the range I call 'data center grade' since the least
expensive model I can find using search tools is about 236 USD.  For
that price I could /buy/ two to three hard drives and get nearly the
same effect by reusing old drives (but wasting more power).

I should be able to find something with a cheep plastic shell for
mounting and a very simple PCB that has slots for older ram of my
selection, and a minimal onboard CPU for less than 50USD; I seriously
doubt the components cost that much.
