If you’ve been thinking you might try and save a little cash when purchasing your new 27″ iMac, by upgrading your hard drive to a solid state disk yourself, after purchase. Be warned Apple has not made the installation as easy to do as it could or should have.
A 256GB SSD upgrade on your new iMac will cost $600 from Apple. But unfortunately doing the upgrade after purchase is definitely not for the faint hearted. The method involves connecting a data cable to the empty SATA port on the back of the logic board, which in turn requires partial removal of the logic board.
If you are interested in performing the upgrade you can read more details on how to complete the SSD upgrade over on the OWC blog
