Is a small closet, 3 x 2 x 8 a good enough size for a server, a router, and 2 external hard drives?
Or will it get too hot in there?
As mentioned air flow is the main concern.
In my room which is way larger then that with a ceiling fan I run 3 PCs, some switches, firewall a router and the temp skyrockets with the door closed. During the cold times it'll shoot up 10 degrees in an hour. During the summer I have to blow cold air from the hallway in here cause it will exceed 95 degrees and stuff starts crashing on me.
