Hi. I have a completely disassembled 2011 iMac 27", I believe I have all the pieces, Core i7, and the 512GB GPU. 32GB ram.
I have a 1TB SSD SATA, and a 1 TB NVME SSD. Is possible (without serious futzing) to install the Blade SSD? I see that I can add another SATA in place of the optical drive, or just under it (a bit concerned about heating issues with the GPU?)
I see I can do the NVME on te 2013 and above, but nothing about doing so on the 2011. Going to give this to a friend using older Mac apps, so MacOS would be no newer than maybe Yosemite or El Capitan.
TIA.

Since it will be asked. I am not sure why the iMac is disassembled. Possibly he had a bad logic board, but got a new one and got frustrated, confused??? Since there is a shiny clean logic board in an anti-static(?) bag, bubble wrap and box, as well as a second one in a bag, marked, "???"

You can run up to Mac OS 10.13 High Sierra.

It has two SATA III (6Gb/s) ports and one SATA II (3Gb/s) port. The optical drive is on a SATA II port so you would be better off putting the second drive behind the optical drive.

You can undervolt the GPU if you want.

It doesn’t take NVMe drives however I have successfully booted High Sierra off an external NVMe drive which is faster than a single internal SATA III SSD.

mid-2011 iMac -> TB(1/2) cable -> Apple TB3 to TB2 adapter -> TB3 dock -> TB3 NVMe drive.

The dock is needed as the TB3 drive is bus powered and the only bi-directional TB3 to TB2 adapter does not transfer power. The dock supplies power to my bus powered drive.

The drive I’m using requires High Sierra or newer and the dock requires Sierra or newer.
