I like it. Lately, my new favorite thing is fanless, or passive cooling PCs. They remind me of the 80s when I was a child and I liked the Amiga, Atari, etc. And those were fanless, while the power supply of the Amiga was like a big brick, so it wouldn't overheat. Only when the floppy disk was working did it make noise. So, now that we have the option of silence again, it suits me very well. By the way, I sleep with earplugs (we live on a busy road) and recently I also got a silent mouse :D.

Due to some mishaps, it took a while for this particular machine to arrive in my hands, as I had ordered it from a store the week after Easter. It didn't go well and now it came from a different store. In the meantime, I experimentally got the Gigabyte Brix GB-BPCE-3350C (rev. 1.0), which is cheaper and weaker, but I liked it too. I have also made an evaluation on that one. I intended for this one to become my main machine, leaving my 7th generation i5 laptop aside. But after searching here and there, I decided to order from abroad another 3rd best fanless. In Greece, there are some better fanless ones, which are a bit expensive, and those are:
-ECS Liva Z2 Barebone (Pentium Quad Core-N5030) for ~182€, the
-Asus PN41-BBC130MVS1 Barebone (Celeron Dual(!!Quad!!) Core-N5100) for ~258€ (previously 232€), the
-Zotac ZBOX Nano CI331 Barebone (Celeron Quad Core-N5100) for ~266€ (previously 205€), the
-Asus PN41-BBP131MVS1 Barebone (Pentium Quad Core-Silver N6000) for ~320€ (previously 251€), the
-Shuttle DL20N6 Barebone (Pentium Quad Core-N6005) for ~388€ (previously 299€.. Shuttle has cheaper fanless ones (N4505), but not better than those with the N5100), the
-Shuttle XPC Slim DS20U3V2 Barebone (Core i3-10110U) for ~686€ and the
-Shuttle DS20U7 Barebone (Core i7-10510U) for ~1008€.

The last 2 seemed very expensive to me, while I didn't know that the rest were fanless, since our own don't advertise it. I discovered it along the way with some research. Most likely I would buy one from ASUS and above (the N5030 is not better than the N4500), but I found a competitive one (with the N100 processor) from abroad before them, cheaper but not branded. I wrote a lot, but I wanted to get you in the spirit.

For this machine (Gigabyte Brix GB-BMCE-4500C (rev. 1.0) Barebone):
I got it the S/O 8GB DDR4 PC 3200 Kingston ValueRam KVR32S22S8/8 memory that GIGABYTE recommended among others, and with a Kingston SSD, the installation of Windows 10 was very easy. It found the drivers on its own, but they were not effective, so I installed the ones from the GIGABYTE website.
In terms of performance, it is quite good, to the point where I could actually rely on it instead of my old i5. Some relatively old games that I ran as benchmarks, it ran them almost like the i5. The games are: A direct 3D version of the old Elite Frontier 1st Encounters, the Minecraft demo, and the Euro Truck Simulator 2 from 2013, Hitman Contracts from 2004, Midtown Madness 2 from 2000 (adapted to run on newer systems), and some others. The truck simulator required slightly lower settings. The iGPU has 16EU (execution units) and 192 Shaders. And the machine runs very smoothly on Windows 10. But on YouTube, something strange happened... It was dropping quite a few frames. I had seen this before, about 6 months ago, on a Celeron desktop from around 2014 that I built for my father. I solved the problem by unchecking the option "Animate controls and elements inside Windows" in the System/Advanced system settings/Performance(Settings) tab. It seems like Windows intentionally makes it heavy to drive out old machines, thus burdening this specific option (maybe others as well). However, the machine we are discussing is about 2 years old and should not have this problem. So, it's a fault of Windows 10. I haven't tried Windows 11 yet, as I have been avoiding it. By unchecking the mentioned option on the new machine, the problem was indeed solved and everything plays smoothly on YouTube, in full HD and fullscreen. The processor is capable, as it has integrated codec decoders for h264, AVC, VC-1, h265 8+10bit, VP8+9, and JPEG. I learned that YouTube mainly plays with AVC and VP9, so there is no problem. The problem is purely with Windows 10 and maybe the browsers (both Firefox and Chrome). By unchecking the mentioned option, the only significant thing we lose is the moving dots on the tabs, indicating activity on the internet. Now, it only shows a static hourglass. I'm not bothered by this loss. It seems fine in terms of temperatures, only reaching 90-95 degrees Celsius with some games, while it can safely operate up to 105 degrees before throttling - thermal core throttling. Additional drawbacks: it only has 3 USB-A ports and instead of a fourth, it has one USB-C port. And instead of a VGA output, it has a mini-display port. It has HDMI, which is good. I like the machine and I could definitely work with it alone. But for example, tweaking Windows settings for YouTube is not for the average user. However, the average user wouldn't buy a barebone system, as it requires some specialized knowledge. I haven't tried it with Ubuntu, but I assume it would be even more comfortable and suitable for a 24/7 server role. *Fanless systems consume even less power than regular mini PCs. Compared to a desktop machine, they consume about 1/8-1/10 of the power!
