iMac 2011 21 inch 12,1 CPU+GPU+RAM+2X SSD Upgrade

Specs:

CPU: Intel i7-2600s GPU: AMD WX4150 4GB RAM: 32GB-1333 MHz SSD: 1TB-256GB OS: Sequoia 15.3.1

Question is, has anyone upgraded the Airport card? Looking to do BT 4.0.

Would this be a plug and play? Wondering if there are any guides out there to get this part working ahead of time while I wait for it to get delivered.

So far the machine has been smooth compared to 4750M and Intel i3. Day and night difference with all the upgrades. All Metal applications work. Haven't tried gaming but hopefully in the future I would be able to.

Anyone can do this with time and patience. It's my first time doing this so it took me about a month, on and off and waiting for parts in between. Hardest part is understanding flashing the vBIOS, my tip would be to get a live USB Ubuntu and flash vBIOS that way.
