I use this build mainly for gaming and streaming in 2560x1440 at 120hz. I play a lot of different games and genres, but some of the main games I keep coming back are Monster Hunter World, CS:GO, Overwatch, Warframe, Quake and Dragon Ball FighterZ, The Witcher 3 and Doom (2016). I'm in huge love Japanese games like the Yakuza series, NieR, Bayonetta, Dark Souls and Sekiro. But I also play a lot of smaller Indie games, where some of my favorites are Ori and the Blind Forest, Hotline Miami, Undertale, Celeste, Journey and Cuphead. I'm pretty excited to use this PC for Ori and the Will of the Wisps, Doom Eternal, Cyberpunk 2077, Death Stranding, Horizon Zero Dawn, Diablo 4 and hopefully Final Fantasy VII Remake.
I wanted this build to be as quiet as possible, so I choose a lot of be quiet! parts. You can count on their name. The Dark Rock Pro 4 is quieter than most AiOs and can compete with almost any 240mm ones. Even under full CPU load, the fans are barely audible. I did some Prime 95 and the temps wouldn't go over 70 degrees, while in folding@home I think I've seen 75 at most. While gaming the CPU sits comfortably below 60 degrees, depending on the game, but I didn't have one yet, that would break the 60s. I have yet to try to stream (x264) while gaming.
The loudest part is easily my GPU. I choose to have a 2-slot one, because I used it in my previous mITX build, so it's not the quietest model around. Maybe I'll be upgrading to a 2,5 to 3 slot GPU, when Nvidia releases the Ampere series GPUs. I've customized the fan curve, so it ramps up really late. As long as it stays under 2200 RPM, the noise bearable. As trade off the GPU temps reach up to 80 degrees, when I've got a GPU heavy workload. If the CPU and the GPU both are taxed, the front fans ramp up and the GPU reaches about 74 degrees.
I had some problems with the case and the mainboard, the I/O shroud is a bit weird, so it doesn't really fit in the case (I'll drop some pictures later).
I can't say a lot about this GPU, it's just incredible for it's price. If you don't need that many threads you can also go for the 3600 (non X!) and save a lot of money.
Monstrous cooler, which can compete with 240mm AiOs, both in noise and cooling, but is a lot cheaper. In noise it definitely has the edge, while it's just a bit behind in cooling. It hinders the accessibility of the PC a bit, but I think this is obvious if you decide for this part.
Incredibly fast SSD, the only downside is the price.
You don't know that it's there.
NOTE: I've got the be quiet! Straight Power 11 650 W 80+ Platinum Certified, that one isn't listed here yet.
Super silent, even at full speed and good airflow.
