Terminal Strips / Bullet plugs for wireing

So I am starting to think through the design of my enclosure for my 12" I3v. My thought is that it would be good to have the power supply, rumba board and Pi mounted on the back of the unit. I was thinking I would like to have some sort of term strip or something where all the wires tot he printer could connect, so that if I needed to pull the printer out of the enclosure to work on it it would be very easy to quickly disconnect everything. But I don't know what options are out there that would safely handle the voltage and current needs, especially for the bed and extruder heating.

Or should I just put the entire printer along with the rumba inside the enclosure and not worry about the temps?
