Well, there's always #15
Thanks for that, it definitely gives some ideas, lots of inspiration there.

Spade bit for the desk it is.
Should I group the stick with the buttons or have the stick at one side and the buttons on the other side?
When I play on the X Arcade I feel cramped during play, and I map player two buttons as it feels more comfortable.
Then I can have my defender button configuration as the stick is 2/4/8.
I'm not sure if I want a large circular hole in the middle of the desk......
I wish I had the cash for something like this, but this is very similar to my monitor configuration.

DB9 to the X Arcade, saves me having to spend £160 for a replacement monitor, and I can extend the use of the X-arcade with all 5+ consoles.
I can spend the money on getting a decent stand for a better screen orientation for all on my displays.
