I've discovered a new use for twisty-ties: keeping the "precision engineered" clamshell halves of my Dell Precision workstation together.
I have to say, I am not impressed with the fit and finish on this machine. I've had it for a year, and just had to have the USB and Firewire ports on the front replace, AND the ethernet jack on the back replaced. All were loose - not that the port itself was coming loose from the board, but any cables plugged in would tend to wiggle, producing intermittent connections. The firewire port came pre-bent up from the factory, but the others developed the condition with normal use. The main door-panel has never been easy to close, and after the technician left yesterday, having replaced the ports, the door was closed. However, I needed to move the machine a few feet. Presto, the door sprang open, and I absolutely could not keep it closed. Enter the twisty tie, threaded through the security lock holes on the door and back panel. Works great!
