New case, episode 2
Looks like I spoke too soon in my previous post. Everything seemed to work after switching over to the new case, but when I tried to play Dragon Age, it wouldn't launch. I'd swapped my old DVD drives for a new one when I changed the case; who knew it'd keep my games from running. Thankfully, I just needed to back up my save files/profile and reinstall the game. It's running now, but I hope there won't be any more surprises making an appearance down the road.
