As for cracking open the case and swapping the physical platters, I have serious doubts it'll work, but the worst that can happen i guess is you'll ruin a new HD too
Apparently HDs are constructed in meticulously controlled dust free environments and sealed on purpose, I suppose a grain of dust riding on a platter will shred up a drive head in short order.
I would try replacing the controller card first but it has to be the exact model#. Try putting the h/d in another machine another bios may detect it. But as or swapping platters and it working you have a better chance of finding a needle in a haystack. To many things can go wrong " Dust as mentioned above, if you knock the heads out of alignment or they scrape the platters while trying to be removed or replaced, even worse it does work but the platers start to oxidize because moisture has gotten to them and your back to where you started.

Send it to a data recovery center. They specialize in changing platters, controller cards, and all that stuff.
Edit
That wouldnt be to bad but, that option usually starts out at 600-1000 bucks saw them talking about this on Tech TV a while back
