Repurposing the iMac parts

I broke some of my mid 2011 27" iMac's logic board sockets while trying to fix a broken GPU. And the replacement graphics card too seems fried now.

Now, I can either buy replacement parts for all the boards (logic board, LED driver board, graphics card) that I broke or, I am thinking, I could salvage parts from this iMac and repurpose them into a Hackintosh of sorts. I am more inclined to pursue the latter since I think that might end up being cheaper than buying replacement parts and definitely far more repairable. Anyway, here is a list of things I already know I can salvage and use them in my new machine

1. The CPU since it is socketed.

2. RAM if I go for a motherboard that accepts SO-DIMM modules

3. The hard drive

4. The optical drive

5. The display using a LCD controller kit.

6. The airport card since it is just a PCIe card anyway. (Is this true?)

Are there any other parts that can be salvaged and reused without a lot of modifications. Specifically, I would like to know if I can reuse the Bluetooth board, iSight camera, speakers and mic. And if yes, what connectors and/or controllers I should be looking for.

Thank you.

Update 1: The built in iSight camera seems like a straightforward USB cam and just connecting the respective wires to a USB type A connector's wires looks like would do the trick.
