Server equipment is not on any normal burglar's list of items to nab. It's such a low risk I think it's completely not worth worrying about.

It's incredibly unlikely they'll know what they're looking at in the first place, and won't be assed to carry out heavy switches and PC gear "just in case" to look it up later. They want to get in, check rooms and closets, drawers, etc and GTFO before you come home or a neighbor notices. Computers aren't as expensive as they used to be. Gaming laptops might look attractive, but other than that you're fine.

They want jewelry, cash, guns, good tools, silver, modern game consoles, expensive bicycles, etc. These are all things that are easy to carry and pawn or sell well on the street. Nobody is selling switch gear at a pawn shop or to random people, so even if they know the value of what they're looking at (extremely unlikely) they'll leave it because it's too hard to fence.

If you're that worried about theft then set up good full disk encryption and have off-site backups of your data (should do that anyways) but you don't need to worry about physical security at home, at least not specifically in regards to your home lab.

Businesses are at much higher risk for hardware theft, from employees or from others that are targeting the locations specifically because they DO understand the value and have a way to offload the gear, but those same people won't be randomly breaking into people's houses hoping they've got Cisco gear in a closet somewhere.
