If not, this is your lucky day to hone your skills yet more. The case front has several pop-out slot covers, allowing you to place the drives where you want. This is where a case with both sides removable proves its worth. The screw holes never seem to line up logically. Don't trust logic, just align your drive so it is even with the front of the case, and do your best.
Some cases provide removeable drive cages, which are very nice.
Remove this, install the drive, then put the whole works back. It will only fit one way. Check the jumpers. Because the hard drive and CD are on their own controllers, set them both to master. Don't force the wrong ones.
