My desktop box at home really is not the most stable machine in the world. It originally had severe problems. I managed to get those under control with tweaking of BIOS options and it actually reached some level of stability for a while. Occasional random crashes, but they were pretty rare. Over the past few weeks, they've gotten a lot more common and have started to include compiler errors too.
And so I've looked at Dell's current desktop line a little… it's amazing how the prices on things have fallen. And it looks like SATA ports are becoming the norm, even if the drives aren't (yet). Which is kind of cool.
