I've done it before. It's nothing special. Accepts standard laptop hard drives. Amusingly the stock HDD my PS3 came with had a sticker on it that said "Not for laptop use" suggesting it was very low spec.
You may lose save data that's on it though so don't invest saves on it if you do intend to upgrade it.
Yah, thing I saw said that means that drive doesn't park its heads when idling so any movement or jarring, bumping, etc., could scratch the platters.

I wont be JB it. Also I still have a prefectly workig PS2 . The £80 one is just normal sized one after the PS3 came out when they took BWC off.
If that's the case, then, stil, buy the PS3 12GB one and just upgrade its HDD. You'll save a couple of euros doing so. If your wondering about hardware difference, then it's small. The newer models consume less wats and cool better than the fat models. Other than that, same ... maybe.
