I had some spare time so I made a relatively simple device that is fairly useful for anti-static. Sure I didnt need it, but after the 3rd motherboard was bad, I decided to take the precaution.
It was relatively simple, I took a spare 3-pin plug, pulled out the neutral and hot wires, replaced them with non-conductive plastic pins ( short ones, its only to hold the plug in place) and attached the ground wire to a round wire loop ( you've probably seen them, used for ground wires).
Hook it up to a case screw and whenever you're not confident that you're static free, just touch the screw. Nothing will help you if you're not careful though.
