Open rack vs. enclosed cabinet

I’m looking to move my servers to a rack/cabinet in a 7-ft by 5.5-ft room. About 6 tower servers, 1 rack server, 4 rack switches, 3 rack routers/telecom, and 3 non-rack UPS.

Would an enclosed cabinet work in terms of cooling? Any general recommendations of open rack vs. enclosed cabinet? Not much literature on the topic…
