Thank you @SpivR for the helpful comments.
Looks like I’m going to wire everything to the downstairs bedroom closet (being used as an office right now)
For those interested…wires with run from the 2nd floor through the attic down the side of the house in a conduit and popped back into the office close from the outside. (Minimizing Swiss cheesing my house).
Looking at either a 9U or 12U rack. The room and closet are carpeted. No plans on doing flooring.
Any ideas on minimizing potential noise ?
Any ideas on minimizing potential heat?
The room has a ceiling fan already.
