How to wall mount a computer?

[vertigox]

Hello, I got a Dell Optiplex 9030 AIO, I need to wall mount it (vesa 100x100), but I need to lock it with a key (or combo lock).

 

I can't find anything!!! Any suggestion would be REALLY appreciated

 

Edit: just found this product http://www.secuplus.com/SP2010NL/tv.html but I can't find any reseller in north america any suggestion?

Most of the VESA wall mounts I've seen use a security allen key to secure it in to place and so far none of the AIO's we've wall mounted have gone walkies.
