Hello Vojta, I recommend one of these, https://fit-iot.com/web/product/mbm2-pro/ Specifications: https://fit-iot.com/web/products/mbm2/mintbox-mini2-specifications/
This is from an Israeli company, sold world-wide. I have three of their computers, I use one as a music server, one as a backup computer, and one as my main computer. My main computer is a IPC2 which they just discontinued, it was available in i5 and i7 microprocessor, what made me pick that one was that it had the larger size SATA drive slot inside the computer, so I could just take my old SSD drive out of the "slow" computer (it was 8 years old) and put it in this new computer. Everything is fast again now with the new computer, the old one is now my backup computer. They get "slower" as software demands get higher, but none of them has ever failed, one reason, they're sealed from dirt in the air, they only draw about 7 watts of power. The AC power supply is external, so no heat from that. On one of my devices, I have the VESA mount and I mount the computer directly to the back of a monitor. They also have larger units, like an i9 computer, but it's $2500. I don't need that. I'm happy with the one I bought, the newest Mint Box was this larger size (and price.) They've announced a new WILD computer with Debian pre-installed. No price is on the web page, but inquiries are being taken. They'll build to order. https://fit-iot.com/web/products/wild/wild-specifications/ Best wishes, David
