Its been a big problem for me, possibly a return type problem. Its sitting on my floor right now because it won't fit into my rack and the next rack I buy will be custom made for my new house this winter. I am assuming most people already have nice racks that they like, so replacing them is not going to be a simple solution. I guess I could go buy some temporary rack, but then that would just add another 100-200 to the price of the 990, not to mention look cheap. Even the racks Outlaw sells will have some overflow, but that looks like it could be my best bet for the time being. I took a picture to show what it would look like in my current rack. Don't laugh.

The 950 is two shelves down for comparison.
Here is just an overhead shot to show the difference in depth.
