Could you elaborate on your willingness to switch to OpenBSD?
I have a small ZFS NAS that I built myself running Linux, and I would like to use it for file sharing and running applications like NextCloud. I prefer OpenBSD and its derivatives (like OmniOS) because it of its security-oriented features, especially things like ZFS and zones, but I have not used it very much so I am not comfortable using an operating system I have not used before for something important like backing up my files.
I would like to switch my daily driver, a Linux laptop, to OpenBSD so I can get used to using it as an administrator, but I worry about OpenBSD being able to support the laptop hardware, especially things like WiFi, BlueTooth, and managing the battery, screen dimming, laptop lid, and so on. I have another Linux computer with a Radeon graphics card which connects to my TV that my children use for video games, and watching streaming video, and I would like to switch this to OpenBSD as well but I worry that it will not be able to run Steam games very well.
