Apple iMAC A1224 Mid-2009 20″ Intel Core 2 Duo 2.00 GHz 4GB 160GB

This Apple iMac sells for less than $150.00. It’s an older model to be sure and there a may faster iMacs but it’s hard to beat the price. The lastest MacOS you can install on this is El Capitan.

The maximum ram you can install is 8GB of RAM and that should only cost about $50.00 to upgrade. You can always sell the older 4GB kit to make the cost of a ram upgrade for a 2009 Apple iMac even cheaper.

When it comes to hard drives you have two options – you can replace the 160GB drive with a larger hard drive like a 1TB hard drive and this should only cost you about $50 to do. But if you want a faster mac and only need a bit more room than the stock hard drive then you should upgrade to a SSD drive. The 250GB SSD from Samsung is a best selling SSD and sells for under $100.

If you do install a SSD you will need a 3.5 inch to 2.5 inch adapter. I recommend the icy dock model as there are no tools needed.

It does take a bit of work to get to to the hard drive to replace it on this iMac model but it’s not impossible.
