The IBM UltraSlim Module Adapter Bay Hard Drive Caddy is only 40$ (50$ tops) on eBay. So with shipping you're talking about 45-60$. And it will have a cleaner finish and has depth in the inner wall to allow tappings the screw to mount the optical drive bracket so you can screw it into the laptop from the bottom.
Once I actually have a need for a 2nd hard drive in mine that is the way I'll go. For now... the 60gig 7200rpm does me just fine. This machine is not used as my only machine and required to store a ton of stuff, I have a Media Server for that. =)

Removing the optical drive is simple, simply remove the 1 screw on the bottom holding it in and them using a small screwdriver push it out from where you removed the screw. Se photo or the 9300 Servie Manual link in my sig:
