I've searched around and read up a lot on solutions for mounting 2.5" drives in the 2009 MP's optical drive bay, but I wanted to be sure that I'm going with the cheapest and most effective one before I buy. I've seen the brackets from Maxupgrades and others, but wanted to figure out which ones have worked out best for you pro users out there. Right now I'm planning on putting an Intel SSD in the optical space and filling the 4 bays with 1TB HDs in RAID.
