Hi there,First of all I bought this on eBay. I recommend buying it on Amazon as the price is the same, and it will arrive at your residence more quickly.OK, are my impressions.First of all, I do not now and will not use Windows. Almost all of these things have Win20 pre-installed. I hooked it up and was able to get Windows 10 up and running (or crawling as Windows is generally slow and resource hungry.The computer only has a few USB ports. Luckily, I have 2 USB 3.0 hubs which work well.Your intrepid neighborhood geek proceeds to install Linux Mint 20.3.I actually had a 1 TB SSD with Mint 20.2 installed, so I thought that would be a breeze. Nope. I ended up booting a USB stick to install the Mint 20.3. Had to press the Delete key while booting to access the BIOS. Disabled Fast boot, and set the boot device to be my SSD. Finally  got it installed with my 2 TB drive set as the /home partition.Got it so that it will boot into Linux and am happy. My main fanless PC before this was a Mintbox Mini 2 pro. You can't find those anymore due to shipping delays caused by Covid. The mintbox is a superior unit, but this will do for the time being. I'll be keeping my eyes open for the Mintbox. If you have some geek blood in your veins, you can install an OS of your choice on an external Drive.
