I built an enclosure for my SO3 XXL a little while back. You can get more details here... http://community.carbide3d.com/t/so3-xxl-mega-enclosure-and-dust-collection/1764/13
Since then I've added
* Gas door springs
* Sliding/Pivoting computer shelf with wireless keypad holder
* Labels for the control panel
I love this enclosure. It cuts noise way way down and contains 100% of the dust, including fine dust.
This picture shows the shelf in the stowed position as well as the control panel labels. You will notice that I remote wired the speed control and light switch for the DeWalt DW611 router. The speed control lets me adjust speed accurate to better than 250 rpms of my target speed. The DW611 has closed loop feedback to maintain the rpm setting under load. You can read how hack the DW611 at the following link...
Here are a few pictures showing the computer shelf in its various configurations...
Rotated into the enclosure to make zeroing easier.
This one shows the wireless keypad removed for easier jogging. the following link will show you how to install a wireless jogging keypad in less than 5 minutes and under $20...
The following picture shows the shelf in the retracted position. This is where I put it to keep it out of the way when I'm not setting zero or jogging. The shelf is just a couple pieces of plywood screwed together and I used some scrap wood to make a track for the vertical piece to slide in. The table top is bolted to the horizontal piece of ply so it can rotate in and out of the cabinet.
