There’s polish Goodram for the ssd and ram, German Recable and Swedish Supra for the cables and Latvian Mikrotik and German Fritz for the router. German CachyOS for the OS, Belgian Servo for browsing and polish GOG for the games.
How about:
- Desktop Tower
- Power supply
- Motherboard
- Thermal Paste
- Monitor
- Keyboard
- Mouse
- Headphone
- Microphone
- Cooling
Desktop cases, you have be quiet! 🇩🇪, Fractal Design 🇸🇪, and a few others too (not made in Europe as far as I understand)
Power supply, you have be quiet! and Fractal (again, not made in Europe I think)
Dunno about motherboard
Arctic 🇩🇪 produces thermal paste, as well as liquid coolers and fans, but not made in Eurppe. Noctua 🇦🇹 is higher quality for coolers, but don’t think they make stuff in Europe either
Dunno about monitors, keyboards (build a custom one and support local suppliers maybe?), and mice.
Sennheiser 🇩🇪 makes awesome wired headphones, the HD 550 are pretty good value I think. They also produce lots of great microphones (the Profile is a USB one). Fairphone 🇳🇱 are the gold standard for wireless audio, replaceable battery and easily repairable parts! The Fairbuds 2 look awesome and the (second gen) Fairbuds XL are also very good. Rode is Aussie 🇦🇺 but they also produce good mics.
edit: EGG (End Game Gear) is based in Germany 🇩🇪 and they make esport-centric mice.
Logitech is European enough (swiss)
Logitech is alright for some stuff, but it’s random chance whether you get e-waste that breaks in the next couple years or something that lasts a decade.
Actually, just thought of one, if you want wired mice, End Game Gear (EGG for short) is good, they are based in Germany 🇩🇪, they do wireless mice too but dunno about the quality of those. Like most electronics, not made in Europe I think.
Custom keyboards are your best bet if you want to support local business.
As for monitors, no European brands I think (Phillips has been Chinese owned for a while, and they never produced outstanding monitors anyways), plus all the panels usually come from the likes of Samsung or LG anyways.
you could add cherry (for mice and keyboards) to the list… german company… and until a couple of years ago they even produced stuff in germany
