Edit after a month or so at the end:After an hour of running the alloy case was as cool as the glass of the table it was sitting upon. My 2011 mini was warm to the touch. I saw (but don't remember) some figures that this thing is a real electron sipper...uses very little power. Would be idea as a 'puter left running to serve as a print server, or even file server, or for remote access via one of the packages that offers that.I was running it in conjunction with a 2011 i7 machine that was, and still it, very quick. Using a Ugreen KVM (bought on Amazon, along with 2 others) and a wireless Logitech 510 mouse with a G710_ USB keyboard plus the download on the mac of the Logitech Options software I was able to operate both the W10 and this Mini with the same kbd and mouse, although pushing a button to do so.The mini was running only the software that was preinstalled. No DVD or even instruction sheet was included. I noticed that on the bottomside there was the black round panel earlier aluminum minis had, but it was not marked for opening...which one did on the older units to add memory or access the innards to change drives, etc.This is probably because there is no point in opening the thing You can't add ram. You can't even change out the drive. It's all custom Apple stuff soldered in place. And for this alone I took off two stars .All I could do with the stuff that came with it was delete stuff I would never use, GarageBand, games, itunes, and other stuff like that. And investigate the newest Safari and mail. Didn't much care for the desktop photos which had nothing to do with Big Sur (where a large piece of CA Hwy 1 washed away into the ocean a few days ago<G>)It's performance with the limited apps I had seemed about on par with a 10 year old Win 10 desktop, haven't run any bookmarking apps as yet.And I'm curious to see how it compares with my two Mac Pros from a decade ago wo have more ram and stuff. But that's for an edit in a couple weeks.It is a very solid and useful computer for the home, and most businesses...but for creative types, publishing, video editing, and such I don't think it's there yet. And the software vendors have yet to get their teeth into OS11. Even Logitech seemed to be scrambling to catch up with Big Sur.-----------------------The basic unit is a shame. 8GB ram and a small ssd, all soldered in place so cannot be undatedOS11 is as buggy as anything I've ever seen.DO NOT BUY THIS until Apple gets it's act together.  And until the aftermarket figures ou how to turn a lowen end lump into something useful. This is NOT useful for me at least.My 2011 Mini is more functional than this POS.
