i did not read all the comments but i had done cage wrestling with servers as a week long event as well as those mid-night cravings that i need to touch the servers just because they are not purring at the right frequency. in addition to all the power, connections, server survival conditions, server security, assisted monitoring (don't rely solely on anyone), etc etc. i also find the need for good nearby parking, large clean bathrooms, available stools or chair, tool set(sockets, big screw drivers, pilers), a place for a coffee break, scream at the VAR and making excuses to the spouse, ULTRA HELPFUL. for small setups and fuzzy architects, these are something as a tech look for in my experience.
