I wasn't sure whether or not to post this in the "Construction Tips" subforum, however since I can't find even a single post on amplifier cases/housings I thought here is a better place to ask.
I'm adapting an old APC UPS box to serve as amplifier case and house my 41Hz AMP9-PS. Space is little cramped with the AC transformer and the amp's board being fairly close. If possible I'll even try to fit my GrubDAC later.
Thing is, with space being a little bit cramped and all, how worried should I be about noise/interference from mains and the AC transformer, both being so close to the amp's board and the signal's path. Should I try to shield the mains and the AC transformer from the amp and the signal wires?
Also, I have few extra pairs of RCA jack connectors... I know they are best used for the inputs, but can also I use this kind of connectors for speaker outputs?
The output power should practically never exceed ~20W per channel, as the the amp will power a pair of Fostex FE207E and a pair of Tang Band W4-930SF.
Another thing is, I plan to use Cat5 or Cat6 ethernet cable (full copper) for connecting the speakers to the amp (as suggested in Full Range forum here). Can/should I use the same for inside wiring? (amp to connectors etc)
And please excuse my ignorance, my knowledge on this subject is very low.

Aluminum will shield electrostatic field but won't do diddly for magnetic shielding. For that it should be steel or better yet, Mu metal.
