Is 60W a lot? I think a system with a few mechanical hard drives and fans will be at least half of that regardless of the processor used. Please correct me if I'm wrong.

It's doesn't have anywhere near the same feature set or polish but I think neolauncher probably comes the closest to replacing nova as far as open source solutions go.
I would go with an intel cpu for the integrated gpu that can easily handle all the transcodes. 12th gen or greater i7 should be more than enough. GPU passthrough for gaming will be trickier. I'm guessing modern games at 1080p which will probably require something with >12gb for some light future-proofing. 6800/4070 class card would be my bet.
The Level1 forums are a great resource for just this kind of thing. https://forum.level1techs.com/c/hardware/build-a-pc/7
https://repology.org/project/thunderbird/versions
It was recently added to arch and then manjaro unstable. It'll make its way to manjaro testing soon and eventually the stable channel.
If you want it now, there's the thunderbird-bin package in the aur.

Do you mind including your budget in the OP? That would help others do their own calculations on electricity savings vs cost of hardware over time.
I've been monitoring this page https://gist.github.com/ironicbadger/5da9b321acbe6b6b53070437023b844d from https://yewtu.be/watch?v=ceUIUyZwchY
It's showing some really interesting results for various processors and their efficiency while transcoding.
