Worth changing from Windows Server to TrueNAS

[philjayj]

I have a DIY NAS running Windows Server as the OS. I'm planning on upgrading to a newer 1u server, but is it worth my while changing the OS to TrueNAS? The only thing this server does is stream 4K movies to six or so TVs.

Oh it's very much overkill but a free server license is a free license

The 1u is a Lenovo SR250. It currently has a hardware raid card but can be replaced with a HBA if I go down the TrueNAS route. I can go months without logging on to the server some times because it just works. I think I'm curious about TrueNAS but also mindful I'm making a load of work for myself for no good reason.
