You really don't need the stock hd cradle. Just make a non-conducting box out of plastic or card stock to place your harddrive on so it doesn't short or knock around. 2.5" cables are easy to come by and cheaper than buying a whole computer. You probably are going to want to buy an ide adaptor at some point to use 3.5" drives (like a cd rom) so there's even more reason to think twice about you spend your money (unless you just want a stock vintage machine).
