Install Hybrid SSHD on iMac12.1

Hi,

My original HD is on the way out and I'm thinking of installing a Seagate SSHD.

I'm looking at OWC to supply and will buy the tool kit as well as the thermal sensor cable needed for this model.

Has anyone installed this or a similar SSHD drive in this model iMac and if so, any problems or recommendations?

Thanks in advance!
