Alright its been a little over a month since the crash.
Main server is running perfectly again, this time hardware raid on Enterprise grade SSDs, with the old consumer ones reinstalled after being checked over multiple times, they are also under hardware raid but not willing to host anything outside of projects I am willing to lose.
This web server still runs across six Raspberry Pi 3b(+) and I plan to keep it this way for the unseen future. Its quite capable, running https, and multiple web apps.
