that all looks fine and you might need a PWM fan control hub

And that's why you use a trash email to sigh up to new games. They can have all access to the flood of spam on that email. It should be normal to have 3 emails. One for business, one for websites/forums you trust and use daily, one for one time off sigh ups and spam

The AX100 has a 1" sensor which is much larger than the typcical camcorder sensors, it will be better in low light, give you a great ability to have a shallow depth of field etc - the RX100 has this sensor
 
Here is a 3 way comparison

An action cam is not a camcorder (or dslr/mirrorless) replacement
 
They shoot good video, but really unless you are actually using them for sports/action shots, they are not a good option and nowhere near the quality, capability or functionality of a proper camera
 
you can correct fish eye in editing, or select a none wide mode on most action cameras

I took the liberty of downloading 3 of the most popular videos showing 4k footage shot with the FDR-AX33 camera and uploaded them to a ftp server, so you can download and view them at your convenience :
Link : ftp://helpedia.com/pub/temp/_fdr-ax33_footage/  The server supports resume and everything.
 
There's MP4 and WEBM versions of each clip. Youtube recompresses every video it receives, so it's not quite the best the camera can record, but still... these are the best versions Youtube has.
In theory, the WEBM version which uses the VP9 codec is better quality due to slightly higher bitrate but decoding it requires more processing power and may not play well on your PC.
MP4 uses the classic h264 codec and uses less resources to play, so if you don't have at least a quad core PC from the last 3-4 years you may want to download those files. 
 
On Windows, the best player (or at least the one I like) is Media Player Classic Home Cinema : https://mpc-hc.org/
 
ps. the files will be there for a few days and then i'll delete them.

I'm not so sure. I'm as good at building a PC (or technical stuff in general) as a five-year-old - maybe even worse! :c What if I make a major mistake which renders all my parts useless? All that money would go down the drain! I'd rather spend a little more money and be on the safe side.
 
Is that Nvidia card really that much better? I mean, the AMD one has 8GB VRAM and 512 Bits, while the Nvidia one "only" has 6GB VRAM and 384 Bits (and it's double the price!). Are there differences I don't know about?
Thank you! The be quiet! Dark Power Pro P11 650W seems like a good choice. It's €100 more expensive than the one I have in my PC though (Cooler Master GX-750W).
 
These graphics cards might be overkill. I can already play at 4xIR (1440p) resolution with my ATI Radeon HD 5000 Sapphire HD5850 TOXIC graphics card (2GB VRAM, 256 Bit). But I want MOAR!
Well, I've read in some forums that the Samsung SSD Pro 950 tends to get hot so it throttles itself. But it's probably good enough to cool the SSD with air.
Seems like a good product and really affordable too!
 
By the way: in my current system my idle temperatures are 22°C for the CPU (AMD Phenom II X6 1090T with Cooler Master Hyper TX3 cooling fan), 50°C for the graphics card and 27°C for the motherboard. Will I achieve similar low temperatures with that airflow case and air cooling in my build? If yes then I might save my money (and potential maintaining trouble) and simply go with air cooling.
 
By the way: Thank you SO much for the helpful replies! I also asked in a German forum but they all told me to come back in six months... >_>
