Long term I'm probably going to rack mount my xr mixer so a passive box in the back hidden with the router etc will be ideal, basically put the box down plug my bass into a jack on a blank 1u or 2u strip with some other bits, USB charge points for Ipads etc, a dual lead that's feeding my in ears and bass and that's me setup!
I'll have a look at the emo boxes then too, thanks BRX.
