iMac 27" late 2009 - Dual mSATA SSD to 2.5-Inch SATA RAID Adapter Converter

Neither device will work in a 2009 iMac. If you want to install 2 SSDs in your 27" 2009 iMac then follow the video instructions in:

http://eshop.macsales.com/installvideos/imac_late_2009_dd/ and http://eshop.macsales.com/installvideos/imac_late27_2009_hd/

In the second video you can install a SSD instead of a HD, simply use the 3.5" adapter kit that comes with most SSDs. BTW, I also recommend using OWC SSDs.

Good luck.

why not working this? This is Mac Compatible. .

Leave your wifi card alone, first the care you show likely will not fit, the same reason the products mentioned in your first post will not work. Macs are not PC boxes, they use hardware specifically made to fit inside. BTW, with all the money you will need to invest in this machine just to install 2 SSDs, why not simply buy a more up-to-date machine such as one of Apple's refurbished iMacs from their online store? If you try to ugrade your current machine, when it's all done you will still have a 6 (almost 7) year old iMac.
