Remember: GeForce3 Ti200. Nothing else. It doesn't matter who the manufacturer is, really. nVidia outsources everything to other companies' fabrication plants. (Smart: they don't have to deal with the consumer demand and they don't need to buy an expensive plant to do it.) You get the same chipset from anyone. There are some manufacturers (like Hercules, who I bought my GeForce3 Ti500 from, though they don't have any nVidia cards on the market now) that provide extra nifty goodies, like bundled software, tweaking utilities, and stuff like that.
The dangers of static electricity are HIGHLY overrated. Just be sure to touch your power supply (while it's still plugged in, but TURNED OFF) to ground yourself to prevent shock. Other than that, as long as you don't have all rugs (rug != carpet -- rugs tend to conduct static much more than carpets, unless the carpet is really deep), there really, REALLY isn't anything to be worried about. Just be sure to keep pets out of the room, if you've got any. You might also want to vacuum out your case while you're in there to improve airflow a bit. Just a suggestion, and not something I recommend you do if you're uneasy about frying components.
And remember, if a board isn't going in, DON'T FORCE IT. Try re-seating it. They take some pressure to put in, but it shouldn't be really excessive (unless it happens to be an ISA extension card, but that's an entirely different story..ugh..). If you can't get it in after re-seating a few times, try varying pressure on the front and back of the card to "ease" it into place. The only part that is a really Bad Idea to ease in is RAM.
Hopefully this helps. 😀
