Hi all i'm just looking for suggestions i'm open to all options. i bought a 2010 21.5/3.06i3/4gb/nohd iMac for super cheep on ebay. I bought it knowing full well no hard drive was included. i'm looking around at options for installing a hd. and it looks like these are my options. I'm also not really sure what else is wrong with it, may have other problems. I know the temp sensor is/was in the missing HD and without it the fans will be screaming. 1.go to apple store and get them to install a new drive (probably going to cost allot/ not sure if they will actually do it, Tell them the drive vaporized) 2. buy standard HD (probably use a SSD) and use software to stop the fans of doom (if I use SSD which run way cooler I shouldn't have to worry about over heating) 3. buy apple brand drive off ebay and hope it is the same mfr as old one (may still have to deal with fans) 4. I've heard of using a external temp sensor and plugging it into the connector. any one try this? I'm planning on fixing this to give to my parents. who really only use mail/browse safari/ pages / iPhoto . very very light use. I'm only in this machine a couple hundred so if it cost me a few hundred to fix no big deal. Thanks in advance for any advice.
