I can relly recommend proxmox. Some years ago we switched from a 60.000€ dell VMWare Storage/Server-Setup to a three Host proxmox Setup for about half the price (to be fair, add 5-10k for Setup for our local Linux Team because we did not know much about proxmox). Mainly because we were able to place one of the Hosts in our Warehouse (connected with 10g Fiber) so there theoretically will be no harm to our production in case of water/fire/whatever in the server room because the one system can instantly take over (after some learning it works Like a Charm). I had some concerns regarding ceph, but for us it has proven Rocksolid, even while we had some real weird Switch issues it always recovered fast and without issues as soon as the connection was there. A big issue were the licensing terms for Microsoft products because with three amd-systems you have a lot of cores to buy licenses for - so we had a good excuse to substitute and cut out some products that only supported Windows environments.

Look into rockwool instead of foam - it does a great Job and is not flammable.

Ne, ich hab kein Bock!

(For anyone curious: This literally translates to “No, i dont have a goat” but is a usual phrase for “I dont want to”)

But my friend often said he dont has a goat on his latin lesson. (Unfortunately this Joke only makes Sense in German, but ill leave it here anyway)

The second scale sounds like a good Idea till you mess up everything due to using the wrong one. I once had a Spirit Level that was for plumbers and had a Second bubble-level built in that was even when the Level was tiltet to about 1.5 degree, great for waste-lines and gutters. Now everything in my House ist tilted by 1.5 degree except the plumbing and gutters.
