rather than cut up a patch cord for this, i was planning a slightly different approach to the RCA connections. i'm sure you've seen the type of structured cabling wall plates from several vendors (hubbell, belkin, etc) that allow you to snap in small connector modules for cat 5, rca connectors, et al. there are also plates designed to screw into a standard electrical box and fit a "decora" style trim plate.

my plan was to use either the small snap-in modules, or perhaps the larger decora-style plates, mounted on the rear of the cabinet to provide both RCA and ethernet connections. no muss, no fuss, no shoe goo.
