Thomas -

Heres the guide to gain access to the HD: iFixIt HD Guide

If you are not using your optical drive, consider replacing it with the SSD instead. Here's the guide to take the optical drive out: iFixIt Optical drive guide.

In either case you'll need a 3.5 to 2.5 bracket (depending on which way you go you'll need different bracket types) and in the case of the optical drive the addition of a optical to HD enclosure Optical to HD SATA enclosure

I would strongly recommend getting a Firewire (if you can still find one, it's getting hard) or USB HD enclosure to house your old HD as a backup drive and using it to prep your SSD. Or use this kit: Universal Drive Adaptor to prep the SSD before you install it.

And lastly, the SSD you get must be able to run at SATA II specs

Hi Dan Are you saying that it's possible to replace the optical drive with an SSD, and that the SSD after that will work as the computor's internal hard drive? If so, why?

Thomas Olsson,

Yes, you are switching your optical drive out for a SSD. Basically your setting up your system with two storage drives one a standard platter drive (HD) the other a solid state drive (SSD). Or, you can switch out your HD for a SSD.

Dan,

As to why - If you swap-out your HD for a SSD you'll need to setup the SSD as a bootable volume (install a fresh copy of OS), then copy over your apps and files. Depending on the size of your SSD you're likely to run into some space issues. Swapping out the Optical drive give you the added function of the HD for less used files. You still need to setup (ideally) the SSD as your boot volume and copy over your apps for the best performance. I would leave your data files (word, excel, music, vids ...) on the HD.

Dan,

Yes - however it is an advanced DIY. Be certain you have the proper tools (every DIY job is easier when you use the right tools).

ID your Mac to find the complete guide.

Yes you can depending on the model number. I managed to replace my existing factory fitted HD with a SanDisk 256GB Extreme II drive on my iMac 27" 2374 model. Replacing the hard drive removes the internal HD thermal sensor which is needed by the iMac and a lack of this sensor will cause the fan speeds to constantly run at maximum.

To prevent the iMac spinning its fan's constantly at full speed some people have used software to override this and there is another workaround! If you have a spare thermal 2pin sensor such as one off an older iMac's optical drive unit (or one purchased online) then you can use this. Carefully plug this into the HD thermal sensor plug (careful not to damage the connector socket) and fix the replacement sensor onto your SSD with sticky tape.

I have done this procedure and confirms this works. The iMac is fooled!

My iMac is 10 times faster running an SSD! and this procedure allows you to maintain your optical drive unit.
