The other trick, if you have a long screw that will fit one of the hard drive cages or anywhere on the case, put that part of the way in, then you can cip onto that I guess. Better than nothing. But mostly, just use common sense, touch the case as you work, don't handle parts by pins or connectors or any chips, and you should be fine. Just make sure you are in one area have a table to work on, keep things in or on top of anti static bags as much as possible, etc. You should be fine.
