It's an Odroid H3 that runs Nextcloud, Jellyfin, AudiobookShelf, a bunch of websites and Home Assistant.
It has 2x Sata SSD's connected.
This setup is not high speed at all, so it's not what you asked about. I just answered the headline question. ;)
If any air ventilation fan turns on in the house it uses at least 3x that power, so I don't calculate the price on my servers power draw as it almost not noticable.
