Very well done :) I have an aversion to sound that borders on a "disability", lol the biggest fights I had with my girlfriend was about sounds (The minute, the repeating and the periodic ones)" The one where we argued if the UPS 20sec alarm two rooms away is "not that bad" or "ice-picks-in-my-brain" was especially dividing. Ex-girlfriends aside... I really like your setup and you are so right about the RGB crap ! Com…

This might be a hard pill to swallow, but if a romantic partner is dismissive of something like “this makes a noise that is really distressing/painful/annoying” there is really only one explanation: this person doesn’t care about you or your well being. Leave now. There is truly nothing to argue about with someone’s subjective experience. Your real argument was about if your well being matters or not.

OP wonders if there’s a version of the Thinkpad keyboard with a metal case. The Tex Kodachi has the Thinkpad layout in an aluminum case, but it’s unfortunately out of stock on the manufacturer’s website:

The Tex Shinobi isn’t metal, so no help there, but it might have a little more rigidity and still has that Thinkpad layout:

I just realized that his tiny screen consumes 120W when turned on. Does any of you have a recommendation for a screen that doesn't consume so much energy?

Are you after a physical tiny screen doing 4K/retina or after something huge not retina?

My LG 38" does 3840x1600. I'm using it since five years now and I much prefer to work on that than to work on my M1 Mac laptop's tiny retina screen. The 38" consumes less than 50W without being set in eco mode.

I was wondering how they can run that cpu without any cooling.. Then they say it goes up to 90°C .. That's way too hot! thats like laptop / mac temperatures. It will function sure, but it wont last, it will degrade relatively quickly.

How quickly is quickly? I've never had a CPU break on me, I still have laptops in storage a decade old that work fine, only they're too slow for the modern web. Perhaps 90C is reasonable for the time you will be using the device.

This specific processor should support an eco mode, minimizing that problem. I'm not sure ofc the board enables the option.

Also relevant for the ryzen 7000 processors, where that mode limits performance minimally but saves a lot of energy. Sadly not on by default, but seems to be a regular AM5 feature now.

I personally would use a regular case with the noctua passive cooler, then add a case fan to only start on high temps. But my setup right now is so quiet it does not seem necessary (5675c cooled by an aio, fans and pumps throttled, noise isolated case - not audible for me on idle and very quiet on load thanks to a low fan curve, set by the excellent fan2go).

This is pretty neat. I wonder what would be the maximum CPU & Ram you can go without installing any moving parts (fan or pump) on a mini itx board. Has anyone got a setup if you want to use more than 12 cpu cores?

You can use a 16 core Ryzen 7950X and cap it at 65W to get 12% more performance than a 5950X. With the additional heatpipe you could do 105W TDP and get 31% more than a 5950X and only lose 5% compared to the stock 170W TDP. It has a GPU built in.

(edit) Maximum RAM depends on the Motherboard. My guess would be 64GB.

Whenever anyone posts anything about their partner that isn’t purely positive, people will come out of the woodworks to tell them to end the relationship.

From this one little anecdote you can’t judge that relationship.

Individual transistors will break, the cpu will continue to work, but it will run slower. That's probably why your old laptops are "too slow for the modern web".

" Some circuits and buses are protected by error correcting codes (ECC). If a transistor becomes marginal—meaning that it works most of the time, but occasionally fails—and thus only causes occasional glitches in those buses, then the processor may continue to function. However, it will likely trigger ECC correction events and suffer performance degradation. These ECC events are a sign it’s time to replace the processor. If that transistor fails completely, the processor may still limp along, but it will not be running at full spec if it does. "
