There is a *darr program (tdarr maybe) that you can use to on-the-fly convert media, but unless you know what you’re doing you’ll just waste power/time over looking for torrents that are already HEVC. Also, depending on the age of the content, HEVC really wont save that much space.

Lidarr and Readarr DO work, but it relies on community support for it to be incredibly accurate (IIRC Lidarr uses Musicbrainz for its backend, and unless someone had added an album there you wont ever pull metadata for it) and takes a lot more time to correctly set up and configure in my experience.

There are a few guides as far as “the best” settings for media, trash guides comes to mind but his guides are aimed at having everything in “the best format” vs saving space

Yep, so one end to the GPU (you may have a spare 6 or 8 pin cable, this is fine it doesn’t get plugged into anything) and then the other end to the Riser

But make sure this isn’t just a GPU cable you have lying around, if it is make sure the pinout is correct or you will blow your riser card

Nah, that connects to your GPU you want to you, not the motherboard

You can make a power cable, the pinout is non-standard, but people have made them and posted schematics online. They do sell them on ebay but it’s a gamble if you get a good or bad one.

Does your XD have the risers with power taps on them? Riser 1 and 2 (or 2 and 3) should have 8 pin power taps that will supply power to your 3060.

Make sure you have dual 1100w power supplies, and the server in a room you don’t use, as the fans are likely to ramp up since the card is likely not a blower style card and the servers fans will work harder to keep it cool.

I’m sure someone else will come along that has more experience than me, and give you some more advice
