Mine too! My Unraid server is a dual-parity 62TB Ryzen 7 1800X with 64GB RAM, and I run as many as 4 Windows Server VM's on it for testing my enterprise software. It's a beast and I love it. I'm actually thinking about upgrading it to a Threadripper 2950X and doubling the RAM.
Limetech's pricing model heavily influenced me for CMC: buy a license once, then free upgrades for life. I was happy with just the NAS functionality (been a user since 3.x days), and then they added VM and Docker functionality for free - amazing company!
I go by Pauven on the Unraid forums too. I also wrote the Unraid Tunables Tester utility, and if I can ever find a free moment I plan to finish upgrading it for v6.
Long story short, CMC runs best on Unraid (but should work on any NAS). The Artwork Caching functionality was designed to prevent Unraid unnecessarily spinning up drives, in addition to improving browsing performance.
