I just finished my cab up using the WG9200. I made a flat shelf that the monitor rests on, I recommend doing this because it is very heavy and having it sit on the shelf makes it easy to put your brackets in the positions you want. Then I made two 4 inch strips using 3/4 plywood to match up to the holes on the front of the monitor, these strips will be screwed into each side of the cab, to keep the front from moving. For the back I used 2 x 6's and bolted the top and the back of the brackets on the monitor. At this point I could remove the shelf but I just made cutouts for cables and cords in the shelf, the extra support never hurts, so now when I put the unit on a dolly the monitor is not budging.
You could use plywood to cut out the face, but I used some balsa type strips from home depot because they bent to go along with the curve of the screen, these were 4 in wide and I had to trim quite a bit off but I was able to get the rounded corners and put them on the unusable portion of the picture tube, so this frames the tube perfectly, add a sheet of lexan and your done.
Sorry to ramble, but the shelf is the key I wanted to point out, by setting it on the shelf, it sets up a pretty nice angle that makes it look like the monitor is tilted...no matter what, your going to be impressed with the 9200, games look great!
