I got annoyed that every time I needed to adjust cables behind the media center it was a disaster back there. So I finally took some time to get it all cleaned up (this was before our trip to Texas, catch-up posts coming soon now that we’re home).
Power bricks are zip-tied to the back of the unit, common-run cables are zip-tied together and hung across hooks. Extra slack is zip-tied up, with enough left to pull the unit away from the wall when needing to access things. Much nicer looking.
