So after hours of searching the correct part and waiting for them to arrive, the mod is complete! What I've done is remove the optical drive completely, used a Vantech hot-swappable tray and made my OWC SSD removable without the need of opening the case all the time. At the same time, upgraded my ram to 2GB, new fan, and OEM Bluetooth card. The main reason I did this was because: A) I have no need for an optical drive (have an external DL drive) B) Want my SSD to be portable. I initially only purchased an 30GB SSD as a test, now that I know everything fits and works I will eventually purchase a larger capacity SSD. The Vantech is a 3.5" external casing with a 2.5" tray. So I used a 3.5 to 5.25 metal mounting brackets to attached it to the original imac's optical bay mounting point. Also purchased off Amazon an IDE to SATA adapter. (Crappy cellphone pics, sorry) Installing Leopard: Now everything is running good except for when I ran xBench for my SSD I was not getting the speeds expected. xBench Results: > iMac G4 1.25Ghz w/ 2GB Ram > > Drive Type: OWC Mercury EXTREME Pro SSD > > Sequential: > Write 10.76 MB/sec (4k blocks) > Write 8.82 MB/sec (256k blocks) > Read 4.71 MB/sec (4k blocks) > Read 9.59 MB/sec (256k blocks) > > Random: > Write 7.53 MB/sec (4k blocks) > Write 9.71 MB/sec (256k blocks) > Read 4.39 MB/sec (4k blocks) > Read 9.87 MB/sec (256k blocks) Not sure if its the Vantech, the IDE/SATA Adapter or the fact I'm using the optical drive's IDE port Drive 1 i believe that is causing this slowness (slower than IDE HDD) The computer doesn't run slow at all, runs the same if not slightly faster? Cold bootup takes 41 sec. What could it be?
