I've been looking at them for a while now, but hesitating
because... not sure why.  I'm using a CoolerMaster case with five
5.25" bays, plus a 3.5" bay external, and another three or four
internal 3.5" bays.  Works great.  Nice and plain and not flashing
lights or other bling.  And not too loud either.  Which is good.

But I've used crappy drive cages before, crappy hot swap ones.  Not
good.  And I think it's time I just went with a 4U rack mount with a
bunch of hot swap bays, if I could only find one that wasn't an arm
and a leg.

Very true.

It's not a bad plan for testing, but using a setup like that isn't
good for actual performance numbers since you'll have too much
contention for IOPS.

Dammit, I just gotta pull the trigger.  :-)
