Got 2 NUCs configured with Stratodesk-based Citrix Receiver installation; needed a special download as the NIC driver in the standard version didn't work. Just need to get registered and associated with a VM to start testing, These are pretty base units, NUC7i5BNX with a tiny, cheap 16 GB M.2 drive and 4 GB of RAM, which should be way more than enough for a XenDesktop instance.
