yeah... the problem is, I don't really trust my Biostar mobo... it seems to be on the edge of stability with my CPU and Ram oced... Maybe I will try this out, I kinda have tasted blood now
lol that made me chuckle, good luck.

Sooo... I woke up this morning and couldn't think of something else, sooo...
First I googled on how to get a stable overclock from my mainboard. I really regret now that I didn't wait until better AM4 Mini-ITX boards had shown up, and immediately shot for the Biostar Board...
The Bios is really awful. I can't set for example the Vcore to a specific value, only offsets. And the ability to P-state-overclock was abandoned in one of the Bios updates...
Long story short, I started with an increase of 100 MHz to the clock, and left all voltages on Auto. The CPU-Z Benchmark just ran fine, but to make sure that the overclock is really stable and works properly, I ran Cinebench Multicore Test right after... Which showed me, that, even when CPU-Z calculated a better score, Cinebench instantly crashed my PC. So, the next step was to increase Vcore, and run all tests again (You can see the steps I made in the table at the top on the left of the picture):
While I left the ratio at 38 the whole time, I fiddled with Vcore and SOC voltages until I had a stable run through Cinebench R15. Finally, I had a score of 4575.9 in CPU-Z, and a stable Ryzen 1700 @ 3.8 GHz and 1.356 V. I reran Heaven Benchmark and got to my surprise a worse score than before. I changed some power related settings in the Bios and changed the Windows power plan from balanced to ultimate power, and then achieved a score of 3332 (bottom right). Just for fun, I reopened CPU-Z, and somehow got an even better score of 4606.6

And with this, I got a PPL-score of 2280611, which beats @confusis score of 2267263
Next I shoot for best CPU score of 4749.4 (@theGryphon with a 1800x @ 3.825 GHz)
Edit: As for temps, during CPU-Z, the maximum was ~74/75°C, but Cinebench cooked the Ryzen up to 84°C... I have to evaluate how it will perform under video editing, compressing and gaming tasks, but I'm a bit careful because I still have the stock cooler, and in that small case, hot air can't escape as quick...

During one benchmark run, I accidentally left Heaven Benchmark in the foreground, which capped the framerate at 60 FPS. Even weirder, in some scenes, it didn't go over 24 FPS. I left the benchmark running and screenshoted the result (bottom left)

Nicely done @GermanDrifter97, @confusis is going to crush us as soon as he gets his 1080 but glad to see you got the high score for the time being.

With a similar Heaven score to mine, he will be at over 3.6m points... No way we could beat that

That 3.5l case is a killer, oh well was fun anyway.

Yeah, it is really small, but I'd rather have a SFX/ SFX-L PSU with enough headroom for hardware upgrades and overclocking potential than an external power brick...
@GermanDrifter97 excellent work I may have to try some more tweaks to my current setop after work today just to close the gap

I had to calculate your heaven score since you didn't put it for this entry though.

Nice @GermanDrifter97 you have the top spot.
Nice job GD!

I'm so sorry, I'm an Idiot. The heaven score is on the bottom right of the big picture (3332), but I calculated with the old score of 3317. Just leave the score as it is, it was my own fault
Better late than never...

Not good enough for the top 3.
Better hardware is not an option currently.
I think there is a way to squeeze the same components in a smaller volume.
Back to the drawing board ...
NIce one! And holy smokes, a 7700k in 3.8l... how are the temps? And what cooler do you use?
The cooler is Zalman CNPS2X. It is good enough to keep the CPU from thermal throttling in games. My goal in this build was to have 1080p @ 60Hz in all games, as light, small and cheep as possible. 2.7kg , 3.8l , fully upgradable = I am happy with the results.
So, I just couldn't let my lead slip away for too long. So I tweaked again. Am currently GPU overclocking in the hope that I gain #1 back
