    I was gifted a 24 inch IMAC yesterday, and I am looking to make some upgrades to the unit. The things I am looking at changing is the HD to SSD, the RAM (max amount), and maybe the wifi card. If anyone has any gotchas or words of wisdom or links they would like to share it would be a great help.

    Honestly, it sounds like you have a fairly solid plan. Pretty much any SSD will work well enough in there, and maxing out the RAM is never a bad idea.

    I'm a bit stuck I've seen these units with DDR 2 and DDR 3 so any direction on the ram modual to order it would be great.

    You need to find out which 24-inch iMac you have.
    System Information will show your Model Identifier. An early 2009 24-Inch iMac will be an iMac9,1
    It will take DDR3, PC3-8500 SO-DIMMs. 2 x 4GB, for 8GB maximum.
    The previous 2008 model (iMac8,1) takes DDR2, PC2-6400, maximum of 6GB.
    So, you need to verify which iMac you have. It will make all the difference in the world :D

    Simply go to About This Mac, and under memory it will show which. For instance an early 2009 might say "4 GB 1066 MHz DDR3". They take 200-pin modules for DDR2 or 204-pin modules for DDR3. Max will be 6 or 8 GB, again depending if yours has DDR2 or DDR3.

    We have an early 2009 24" iMac (9,1) and definitely upgrade to 8 Gb memory first. It's easy and cheap, and IMHO makes a significant difference. The SSD upgrade seems to be a lot of work and I haven't felt the need to do that one yet.

    *UPDATE*

    I just upgraded the ram today to 8GB i see a small boost in performance things to have smoothed out. I have an EVO 850 here also, but waiting on a few told i ordered on Ebay to come in.

    Ok I am finally getting around to swapping the hard drive out. Th ought I read somewhere about a thermal sensor issue once the HD is swapped out could someone speak to that or is it a simple swap format install and enjoy the boot in speed?

    There are various threads on this, and I'm not 100% sure, but I *think* that your model has a separate thermal sensor that's tacked or taped onto the hard drive. If that's the case just stick it onto the SSD and you should be fine.

    I thought I saw those threads, but for some reason when I did my search it didn't pop up like it did before. Thank you for the reply.

    *Update*
    It looks like the Early 2009 (mine) is an easy swap, and the late 2009-2010 require the mod (software or hardware).

    I did exactly what you did with my 2009 24" IMac.
    There is a thermal sensor attached to the hard drive, and when you do an SSD upgrade, the fans spin at full speed as they think the hard drive is overheating. I know you can do one of three things:

    1) You can buy a kit from OWC (it is bundled with an ssd and a lot of tools) - so EXPENSIVE; https://eshop.macsales.com/item/OWC/KITIM09HE2TB/
    2) You can "short out" the hard drive temperature wire and it may stop the fans from running full speed; http://blog.macsales.com/19617-diag...ed-issues-after-upgrading-the-main-hard-drive
    3) You can install a program called SSD fan control, allows you to manually control the fans. This is what I did personally on my 09" and it works great. http://exirion.net/ssdfanctrl/

    Thanks for your report :) But that is for LATE 2009 models (iMac 10,1 & 11,1 : 21,5" or 27"). You don't need that on an early 2009 model (iMac 9,1 ; 20" and 24").

    Which model do you have ?

    I wasn't thinking very well when I posted my earlier answer ... I forgot that I have indeed done this swap on an early 2009 (9,1). I simply removed the (outboard) thermal sensor from the hard drive and stuck it onto the SSD. Works fine, no fan problems, no need for kits or fan control apps.

    Later models didn't use a separate outboard sensor and that's when you have to get into some trickery.

    Sorry! I misread your post and assumed you had a late 2009! With the early 2009 you will be fine :).

    Well after a lot of delay and second guessing I completed the upgrade last night without any real issues. I saw the wifi card in this guy and got me to thinking if there is an AC upgrade to this unit I can buy?

    Those machines can still be useful beasts. I have an early 2008 24" iMac that I still use on a daily basis. 6GB RAM, 256GB SSD, and 10.11 make this machine absolutely fly!
