I very much believe in the concept of building for a task instead of over-building something to levels you don't need. Such is the case with this PC, centered around the SilentiumPC Brutus Q20; an mATX chassis with a tiny footprint (and horrible airflow in its native form).
The Athlon 200GE, coupled with 8GB of average 2400MHz DDR4 RAM, is perfect for the tasks this computer will be expected to perform: run Netflix, open a word processor, feed an internet browser and, once in a while, play a light indie game or emulator. Yes, the BIOS on the Asus board I used allows overclocking, which I took full advantage of, thanks to a leftover Wraith Spire cooler from a Ryzen 7 build (can be found online for 5-10€). It's not stable above 3.9GHz regardless of how much voltage it's given, so I pulled it back to 3.85. All temperatures are with an ambient 20°C - as you can see, it's an incredibly cool-running chip.
Cable management was a bit of a chore, and I wish I had splurged on a modular SFX power supply (+bracket) but, alas, I wanted to go cheap. With the Cooler Master 500W PSU, I always have the option to put a more powerful Ryzen CPU and a dedicated GPU into the build.
Heat management (or lack thereof) was taken care of by some extra long bolts and nuts, spacing out the top plate. A 120mm fan barely managed to be bolted into the bottom of the chassis (no, there is no fan mount) to provide bottom-to-top airflow, inspired by the trashcan Macs. That's pretty much all there is to this thing.
Also, I didn't have "proper" tools to build this so...m excuse the butter knife screwdriver, the pocket knife zip-tie cutter, and the beheaded toothbrush I used to help plug the ATX power connector in (the board was flexing, I used to for counter-pressure from the bottom).
Love this little chip - easily overclocked to 3.8GHz, where it performed MARVELOUSLY. The Vega 3 iGPU is alright; makes quick work of all light tasks, and can play some games decently as well.
Look, it's basically the exact same thing as the Ryzen-3 2200U, just with an increased TDP and power limit. It performs great for the money, and it's incredibly easy to cool.
It's a solid board - I wouldn't trust it to overclock a 6/8-core too far, but for a more budget-oriented build, it's hard to go wrong here.
