There was an odd instance with the Wi-Fi. Since you asked I got curious and moved both displays to the Ministack and couldn't tell any difference with the displays. I have an Apple Studio Display thru a TB port and a 24' Apple Cinema using mini-display-port with a USB-C adapter both attached to the Studio. I haven't done a really large panorama stitch since it got it yet and expect that ought to get the fan going, but just normal editing it's completely silent. A lot of people are complaining about high pitched whining from the Apple Studio units, is your ok?

I'm not particularly anal about a little bit of fan noise so long as it's not excessive.

With the HDD in the Ministack cranking away how is the noise from the Ministack? If I have a Mac Mini attached to the Ministack, do you (or anybody reading this) know if I can attach two 4k monitors to the Ministack or will I need to attach one to the Ministack and one directly to the Mac Mini?

It's good that some of the latest USB-C monitors are also hubs so that's gonna give me some extra USB-A ports meaning I can probably live with the lack of additional USB-A ports on the Ministack. I'm gonna buy a HDD separately as I find OWC's prices a bit steep, I'm half Scottish! I'm thinking of buying one of these along with a Mac Mini as the mini is particularly lacking connectivity ports, so thanks for posting your first impressions. Ok, I just got the OWC Ministack in the 14 tb version. Probably costs too much for what it does, but all in all I think I'm pleased. Couple of USB-A ports would be nice, but I didn't really get it for a dock, I just liked the looks of the housing as a space saving way to add another disk drive. You lose one of the TB ports connecting to the Studio, so you only get an extra 3 TB ports. Seems like it takes kinda longer to boot up than I would have expected. No on/off switch, it goes to sleep when the computer is turned off but the light stays on. The black finish has a nice texture and looks good, but personally I think they missed a trick not making the finish match the Apple finish. Still, looks like they could have done better. Kinda spoils the cosmetic effect, but it's not particularly visible with the Studio sitting on top of it. The black aluminum case looks good, except for the top plate which is a kinda crappy looking sheet of black plastic. Of course the Studio tries to slide around on top of the Ministack. The rubber feet on the bottom don't slide around the desktop like the Studio does. No Wi-Fi interference with my Studio M1 Max sitting on top of it. Ok, I just got the OWC Ministack in the 14 terabyte HDD version.
