Breadboard deluxe

I'm starting to be a bit annoyed by the mess on my desk. The small breadboard that are connected to a rpi or an arduino is not easily moved.
Thus I want a better setup with a more permanent breadboard that can be lifted of the table in one piece.

What I want:

• Large breadboard, two 840holes should be enough. 
• Power supply with shutoff switch. 3.3 and 5 v.
• Hidden permanent raspberry pi with pins close to the breadboard. WiFi and separate shutoff switch. Access to the sd-card.
• Hidden permanent arduino with usb connection and broken out pins. Also shutoff switch. 
• Voltage measure probe with screen. 
• Led light 
• Programmer
• USB hub with single connection to computer
• Common ground for everything.

I'm thinking that it would be nice to have a wooden board to connect everything on and mount the arduino and rpi on the underside.
