Already did that. Got everything working. I have an external 500 GB drive partitioned into 2 250 GB drives: one for OS9 and the other for OSX -the two lowest drives. The new internal storage is also 250 GB. I left the shielding off the back of the DVD ROM and new SSD; it only gets in the way.You may have to unmount the dvd drive and loot at the top label, they typically show there if not imprinted into the metal casing.
