I wish every apartment would have at least some units of at least half-depth of rack space. Fitting anything (even a basic setup of a PaspberryPi + the PON modem + a minuscule switch + a PoE inhector) into the tiny space behind hatch where the cables from all the wall sockets end in my condo apartment is extremely hard. And I am still looking for a 5-port switch which would be manageable, support vlans, handle gigabit ethernet and inject PoE if possible while being really small.
