Replacement parts

Hey there.
I recently bought a replacement fan and installed it yesterday. Since I had to take the drives out to do it, I think something may have gone sideways on me. I put the drives back in in the same order I took them out…and was very careful how I did it. In other words I didn’t man handle anything. Any way, the machine would boot. I’m figuring it had a kernel panic but I’m not sure. I just didn’t have the time to investigate it fully by commenting out the drives in fstab and trying to boot again. So this is pre-emptive question. Assuming that the drive slot board got damaged in some way where can I get a replacement if I needed one?
Thanks

I assume you have this working again?

It is. Thank you. Although I may have installed the fan upside down. Ha.
