Mounted my new Asus VE287Q Man the Obutto pit rocks! Will post finished pics soon.
Here's a tip that worked out well for me- Since it is my desk and pit, i use the swivel keyboard tray. I didn't want to have to adjust the tray height each time I needed to use it. My solution:
3/4" PVC coupling. I measured the difference between the pole fully inserted and where I wanted it. In my case it was 2.5 inches. I put one 2.5" x 3/4" coupling into the mount tube followed by a greased washer. Then put the tray mount pole in. Now my keyboard swivels around and is at the right height each time.
Also, since I have to remove the center stick mount to use the keyboard, I did the same thing there. This time it was 4", so I got a 4"x3/4" coupling and inserted it. Now when I drop the stick mount in, I don't have to fuss with getting it's height right. It's the same each time. Regular 3/4" PVC will work just as well, but the coupling were cheap and the right length was readily availible.
