Hello all, First let me assure you I have searched through a good amount of threads and I am still struggling. I have recently upgraded my late 2009 iMac from SL to ML. I decided it could do with being a bit quicker, especially after my recent purchase of a MBA with a SSD. I have read that it is perfectly possible to install a second SSD in the late 2009 iMac in the optibay but this is where I need clarification. 1. Parts seem to be few and far between in the UK, the only adapters I could find are: http://bit.ly/QYKI9I - will this fit? 2. With the adapter above, do I require a special SATA adapter? 3. Do the fan speed issues occur when installing a SSD into the optibay or is this with replacing the original HD? 4. Are there any generic adapters in the UK for making the optical drive external? I've seen a few on the Internet but wasn't sure if they are specific to the apple optical drive only? Many thanks for help on the above, this could be a very cheap upgrade for me considering I can pick up a SSD for £30! Thanks again, Stuart.
