You'd be far better off to figure out which logic boards are good and sell them by themselves on eBay or whatever.
Besides, no one wants to buy a used hard drive with a broken seal.
This project is gonna come back to bite you in the ass if you proceed with it. The chances of a) you repairing them successfully & b) the drives operating successfully for more than 5 minutes are slim at best.
Worst case scenario is that whoever you sell them to comes back and sues you if they lose data and find you sold them a defective product. You may end up with a lot of pissed off customers, which in the long run, will destroy your reputation and ruin your business, all for the sake of making a few bucks on a whim.
Don't be offended by my posts, but jono is right, you dont know enough about what can go wrong here. Remove the PCB's and sell them on ebay, it's the only way you can get out of this positively.
Why do you think somebody sold you 25 of them for $40??? It was a great way for them to get rid of a load of scrap!!
