Enthusiasts and early adopters either already have compatible systems or would go for (3) or (2). And I've installed several CPUs with fans and heatsinks but am not a "hardware hacker"--I don't even own a soldering iron. And if your system has a TPM connector, it would be silly to pay someone else to connect a TPM to it, and if it doesn't then it would be pointless. "Sit on Windows 10" Sounds good to me. It's not "giving up" unless I try something else and fail.
