I originally purchased this little PC for my Amateur Radio hobby to connect my radio and RF amp etc. It has everything an Amateur Radio enthusiast could ask for with its 6 Com ports. I purchased the i7 version with 256Gb ssd and 4b RAM but always had plans to update the RAM. However I also use Freecad to design models and I was thinking about trying out Linux as an OS. So With these to consider I want a bit mad and updated the RAM to 64Gb (2666Mhz) and purchased a 1Tb M.2 SSD for Linux and a 500Gb mSata for Windows 11. This little PC is more than good enough for what I use it for. I would advise that you need at least 8Gb for Windows 11 depending on your needs and 256Gb ssd should be enough depending on your needs. The seller is very good sending me a message when I ordered the PC to make sure it was the spec I wanted. And also sending me a message after it was sent to me that I got the order and was happy with it.
