Have you actually seen the dust accumulation under your average reception desk? Especially if there's particle board anywhere in the mix (the tabletop, the side cabinets, the drawers, any back panels...).
If you don't have a room where you can safely keep your network gear, you can at least keep it organized and away from grabby hands with a wall-mount enclosure like this: https://www.amazon.com/Tripp-Lite-Enclosure-Switch-Depth-SRW6U/dp/B003K1NFY4
i really think you are putting too much worry in to it. Neither of my kids ever bothered any of my PCs or game systems. But if you are set on doing it then you might as well do it right. put the gaming rig up on the wall next to the TV or put it in a locking rack cabinet. Something like this 6U tripplite would do the trick

Well right now my NAS is 2 feet from my security camera Takes 30 seconds to pull out a couple of harddrives and bye-bye recording data.
With a cabinet they'd need to drag a much bigger fixture, one that's possible corded to a table, down 3 stories.
I mean it's still possible to remove the disks, but it ups the level of effort A LOT and thief are usually lazy and less likely to have the tools to get into something like this: www.amazon.com/Tripp-Lite-Enclosure-Switch-Depth-SRW6U/dp/B003K1NFY4
I just have no idea what to buy because I'm ill-researched.
I should probably clarify, no room for a 2 post rack/large enclosure. So a shelf by itself probably wouldn't work.
I was thinking something like this that will sit on the ground, table or wall mount, but designed for non-rackable hardware (if it existed): https://www.amazon.com/Tripp-Lite-Enclosure-Switch-Depth-SRW6U/dp/B003K1NFY4/ref=sr_1_4?s=electronics&ie=UTF8&qid=1503435413&sr=1-4&keywords=6u+cabinet
Problem is all the hardware we will be using isn't rack mountable. We've used something similar in the past with shelves, but things end up falling all over and becoming a mess. Plus they are excessively large for the size equipment we will be using.
Yes, I'm impressed with the quality, especially considering the price. https://www.amazon.com/dp/B003K1NFY4/ref=cm_sw_r_sm_apa_glt_fabc_CR0FXK73B5BNN5SEBGNC?_encoding=UTF8&psc=1
Use something like this to keep it all contained and neat. Will give you an easy place to mount fans if needed too. There are larger ones if you need to go larger. I have the 9u and its great. It can be mounted at ceiling height so it effectively takes up no space.

I would suggest something like this:
Tripp Lite 6U Wall Mount Rack Enclosure Server Cabinet, 16.5" Deep, Switch-Depth (SRW6U),Black https://www.amazon.com/dp/B003K1NFY4/ref=cm_sw_r_cp_api_i_aZhCFbHF7S1K9
Honestly i5 will probably be fine. Milestone's own husky NVRs start with i3's and only the higher end models use i7s, their 20 (1080P) camera models use i5s. SSD for system drive, WD purple for the recording, 8GB ram is fine. (Now keep in mind it pays to have a nice nvidia on the system you will view the streams on; milestone/blue iris etc are server/client based systems so your normal PC can be the "client" you connect into the server on).
Anything with quicksync. Core ratio is generally 2 HD cameras per thread/virtual core. However that's with running motion/analytics on each stream. You really don't need that. I just run 24/7 on my front 2nd story 4k and my back yard 4k with basic motion detect, then motion only recording in my side alleys and front door. (and those are set to only I frames at 12% of true resolution, only checking every second).

What I would do is find a used 2u; 3u; or 4u PC (server mount sizes). That way you can have a really nice clean professional setup. You don't need a server rack itself to start. (That's really all these enterprise level "NVRs" are anyway, standard server mount ATX case and desktop PC parts running windows server or linux, nothing at all fancy in them, but sold for 4 times what it costs to build or buy used)
Just grab a nice used box with a "u" size, then add your POE switch (40-80 bucks depending on # of ports powered) and they can stack ontop of the flat wide server box (it's like a beefier NVR/dvd player proportioned "box"):
Get all your wiring up and organized with runs to a nice basement area with a flat wide UPC (again 2u/3u "server rack mount" type)
You can get "u" mount brackets for smaller switches/routers that aren't that form factor and stack it all with nice spacing and cooling in a really clean setup.
Eventually buy one of these and wall mount it locked up etc with nice cooling, totally out of the way: https://www.amazon.com/Tripp-Lite-Enclosure-Switch-Depth-SRW9U/dp/B003K1NFY4/ref=pd_sbs_147_2?_encoding=UTF8&pd_rd_i=B004VUOAPG&pd_rd_r=42450040-092c-11e9-909f-2fe01a604df2&pd_rd_w=JRpMd&pd_rd_wg=q2A9Y&pf_rd_p=7d5d9c3c-5e01-44ac-97fd-261afd40b865&pf_rd_r=NSF8G39EXKG4A6HBWFB4&refRID=NSF8G39EXKG4A6HBWFB4&th=1

I'm planning on buying from this Tripp Lite series when I finally get serious. The depth will accommodate most switches and it looks like it can fit this UPS.
Obviously the benefit here is that you can get standard 19" shelves, patch panels, etc. The downside is that rackmount servers aren't going to fit given the depth, however your case should fit just fine.

It's solid and very nice. For a home setup I think it's pretty darned good.
