Yup; here on the 42" Leviton panel none of the catXX cables go into the panel from the top, sides or bottom. It is mounted on a piece of plywood with 2X4 wood braces. The cabling goes behind the wood between the 2X4's and out a hole punched out in the can where the patch panel is. The only place you see the cables are on the top near the ceiling / where the wires are dressed. (bundled). I did exceed the 24 port capacity of the switch / Leviton multiple tiny patch panels way back. The above noted I am using short hooded (which I do not like) patch cables to the switch. The cover fits over the Leviton mini patch panels with room to spare. The network switch / LED's face down making it it a bit difficult to see the LED's but its not really that much of an issue as I went to a tiny managed Gb switch there. Nonetheless these are made to fit in the can with the top (lid) on. Outside of a can they look nice; but expensive for their port capacity (24/12 ports / total spend = $port). Similar sort of to the tiny 24 Gb port managed switch fitting (DIY fitted) into a small space in the can thing you see folks doing here. ((24 Gb managed ports tiny space / total spend = $port)).
I did exceed that 24 port capacity a while ago, going to the outside and adjacent to the can in two locations. One location now is just a rack with servers, another switch, routers et al which nearby but some 25 feet away now in a "server section". Note this is only what I did and mostly cuz I had the space to do it. (I am close to 1/2 of a class c of network devices on this network and it is a bit much for a house I guess).
The other house and mostly due to much less space and WAF fit everything in one closet (2 cans) which is in a closet in a closet. There the can is very tight. I did put the wireless access point outside of the can. Its been a few years now and I did push on the space. Its not easy to get to the LV stuff, servicing it a real PITA. But it looks nice and very "pleasing" to the eye (well the WAF too) and I never have to service it and I do not need to change anything with it.
Well I lost the wireless AP (access point) last year which is out of the box (can). I had pushed the power on the radio to some 100mW versus the off the shelf 25mW. I really didn't need to. Replaced it and set the power to 40Mw. (and that is probably too much). The AP though was connected to a wireless weather station "server" (which was connected to proprietary wireless to the weather station on the roof). I did shut off the wireless piece of the server and just put the server in the closet connecting directly to the switch with a wired network connection. I should have done that in the first place.
