I'm a med student and I use my mid-2010 27" iMac mainly for studying and accessing school/hospital/clinic material that I need. I'd like to try and hang on to this computer for another couple of years before upgrading. It does everything I need and other than a flaky 1 TB HDD it works great. The HDD "failed" at one point and I was able to finally erase and reload it. Disk Utility reports everything as fine, but SMART Utility reports the drive is failing. To that end I'm going to remove the 1 TB HDD and replace with an SSD (only need a 128 Gig SSD as I'm using about 70 gigs of space total). What bracket and SSD drive are best? I've looked at Crucial and OWC. Not sure which bracket I'll need. Looks like replacing the HDD will be somewhat easier than trying to mount the SDD in addition to the HDD. I really just want the HDD out. I have only 4 gigs of memory and was thinking of putting in 16 gigs more (20 total). Can I just put in a couple 8 gig DIMMS into the two empty memory slots? And is there anything to be aware of when getting more memory? Does it have to match anything or be specific in some way? For instance, would this work? http://www.amazon.com/Corsair-Chann...F8&qid=1354469337&sr=8-5&keywords=imac+memory Anything else that I could potentially upgrade while I have the thing open for the SSD install? Thanks in advance.
