I've found several critical issues on the Gigabyte Brix S GB-BSi7HT-6500:
1) The power supply makes an audible noise also depending on load.
2) The power supply and the case generate high electric and magnetic fields, which cause me head and chest pain. Gigabyte devices are not shielded properly, it is a very big health issue.
3) Asus MB169C+ monitor does not work with your Thunderbolt port (it requires USB-C|DisplayPort Alternate Support).
4) Product page says it's Thunderbolt but the case only states USB3.1.
The biggest concern is the emission of uncontrolled electric and specially magnetic fields, whatever the frequency it is. The bottom of the GB-BSi7HT-6500 is the only part made of metal, specifically ferromagnetic metal, which seems great. However, the sides and the top of the housing resemble polished aluminium but in the end it is merely plastic.
Very dissatisfied with Gigabyte, I though they aimed to higher quality standards. I cannot recommend this brand anymore to anyone.
