The piece of hardware that was chosen for the avionics-adjacent software I was working on was chosen before any software was written, which was 3 years before the plane was 'supposed' to fly, and 5 years before anyone sane expected it to be in service.
Irritatingly, they didn't even pick the top-of-the-line machine from the vendor at that time. They picked a middling one. And then put an LTS OS version on it that didn't fully support the motherboard chipset. I spent way, way too much time an energy trying to get the software to run on the sort of timescales necessary. It took me months to get anyone to let me talk to the vendor in order to sort out the fact that the storage was being run in legacy PATA mode, reducing our IO throughput by an order of magnitude and the application throughput by about a third.
Ten minutes on the phone and I got them to agree to give us a patch that aliased the chipset to one it was backward compatible with, that was actually supported by the OS. But they really wanted us to take the never version of the OS that didn't have this problem.
That's not even the most hard-ware crippled I'd ever been, but it was top three.
