Computer Straps

[Moosh]

Hey guys. I work at a University and I need to get computer straps for a new lab. The computers in the lab are mid size Dell towers, Optiplex GX270's. I wanted to know if there are any good sites where I can order computer straps so i can secure it to the desk. I am also ordering security locks, but I need the computer straps because the towers have to be strapped into the desk. Hard to explain I don't want any $30 lan party type straps, just basic ones that get the job done. Remember, I need about 30, so 30 * $30 seems like a bit too much.

Thanks
