ATM I’m looking at making space well used. The HAF Stacker always appealed to me for that reason. Have my dev machine on top of my crap machine on top of a mac pro I moved into a better case etcetcetc.
I have been seeing people shit on the case recently, which really annoys me. Because, to me for my space constraints, that thing is godly. Its not a christmas tree case that will shatter when you move house.
So. Is there any case out there that is designed the same way?
Ah, you want the small cases, not the big one. Gotcha.
Even the smallest ones of the Core series have the mobo on a separate tray somewhere in the middle with the PSU under it.
Core 500 not so much, as the buttons and USB ports are on the top and would be inaccessible when stacked (unless @FaunCB is intending on running the systems 24/7 an not using the front USB ports).
Are you looking for something like the Silverstone GD07B/GD08B/GD09B? All IO is front or rear and air intakes are on the sides. The tops are solid and they have feet.
I don’t know of any case currently on the market that interlocks.
