PS: In Case you are into 3D printing or willing to try that (from your
own  description you are not into HW/building - I know...)
There is a nifty design of a 2-3U rack for up to 14 Pi's which may take
30+ hours to print but would be providing you with a rack mount (add the
PoE Gigbabit Switch and the PoE splitters and you are done...

I would likely re-design the design posted on thingiverse - but it seems
a good starting point...
