You need to contact support and push them to ship your units ASAP. I demanded cancellation of my order and full refund. They offered $30 refund (which I haven't yet seen credited to my account) and shipped 2 of my 3 units out immediately. My pre-order date was on Jan 30th. So they're not prioritizing by order date. It's weird as you should have yours before me. Those screams the loudest will get their shipment out. Seems like those who order multi units like you and me are being pushed.That's exactly what I'm weighing right now. The noise can be mitigated just by moving the rack to another room, but I'd have to knock some holes in the wall and run cabling to another location. In my case, the room would be on a different floor and the noise wouldn't bother me as much. I could also leave the rack where it is, and build a cooling+sound solution around it. Also, not ideal - and time consuming to boot. The other problem is, these old servers don't have any 10g networking or NVME, both of which I've decided I really need. Running a Proxmox/Ceph cluster on consumer class SATA SSD and 1Gb nics is really a bad idea.
I'll give Minisforum til mid next week. If I don't get a shipment confirmation, I'll just cancel the order and go a different direction.
