I finally did a long-planned upgrade: I replace my 5+ year-old 20GB hard drive with a new 250GB Seagate SATA drive. The install went flawlessly. I was nervous, I've read about people having problems with SATA installs. I probably didn't have problems because I read so much and knew about the pitfalls and how to avoid them. It's worth noting that the 20GB drive I replaced was one of the oldest components in my system. It's one of the few devices that date back to the original computer I bought in 1999 (along with modem, sound card, and speakers). So, this was somewhat historic in that respect. The old drive was actually still performing quite well, I'm very impressed with that drive (it was also a Seagate). I just wanted a bigger, faster drive. I plan on hopefully re-using the 20GB drive in the future.
