I've returned tons of computer parts under warranty (worked in a computer store for a while) and many times I got free upgrades...
IMO, the best are hard drives. I just RMA'd a 160gb hard drive (Seagate) for a coworker and got a 250gb as a replacement..
But, battery back-ups are also nice.. I just RMA'd my 2yo Belkin 800VA ups and they told me they're shipping me a 900VA as a replacement..
Graphics cards.. meh.. one time I returned one that wouldn't overclock at all (had artifacts even at stock speed) and got one that would overclock a TON.. like more than most could get out of it. (A Radeon 9500.. overclocked it to 9700 hard mod.. and then wayyy past 9700 pro speeds.)
I think you get the best chance of upgrade with hard drives, though.. Right around the 2yo mark, hard drive makers stop making the lower capacity drives so they just send better ones.
EDIT: You fvcktards, I'm not talking about fraud. I'm talking about warranty replacement as in warranty replacement.. or what I originally said.. CLEARLY. I would never commit fraud. When a part breaks, I return it if it is under warranty. Often, companies replace said item with a better item.
