Question about ASUS ROG Strix G15DK

Hello Mr/Mrs Anonymous,
First of all, here are the exact names of the hardware elements:
Motherboard - ASUS PRIME B550M-A (WI-FI)
M.2 NVMe 3.0 - WDC PC SN530 SDBPNPZ-1T00-1002
HDD - Toshiba DT01ACA100
RAM 2x 8Gb HMA81GU6DJR8N-XN (DDR4 - 1600 MHz)
GPU Nvidia Geforce RTX 3070

The case itself is full to bursting as it is delivered. So it is not intended to tinker with it.
But I did it anyway and found out that the second M.2 slot is occupied by the WI-FI chip. By the way, the second slot is directly under the graphics card, so you have to remove it first to get to it at all. Since I don't need the WI-FI, I unplugged the thing and installed my M.2 from the old PC in the new one, which worked great.
What might also interest you is that the motherboard already supports the new PCIe express 4.0, but the installed model is still from the old M.2 NVMe PCIe 3.0 standard. (Theoretically, 4.0 can allow twice as fast a transfer as 3.0). The "free" slot can only take memory cards up to 80mm long, the already occupied slot could take up to 110mm. (So be careful what type of slot you have/buy if you also want to fit a memory card there).
The operating system is installed on the built-in M.2 memory, so a few GB of it are already occupied.

I also installed my old SATA6 SSD 2.5" hard drive and pushed it into the lower part, where all the cables are hidden behind a metal cover. (It's pretty full down there) So it's not fixed at all, but it won't slide around because it's so squeezed in. (I know, it's a bit unprofessional, sorry. :) )

Otherwise, the box works great. I wouldn't overclock the device either if you don't know enough about the subject. There is an "EZ" mode, for the stupid, but it hardly makes a difference. The biggest difference was that the fans just ran at 1800rpm by default (which you can hear a bit) instead of 1200rpm and the clock frequency was always around 4500GHz. Standard mode in comparison has 1200rpm (at that speed you practically don't hear them) and a frequency that is at about 3800GHz, but as soon as power is needed it goes up to just under 4500GHz. (Tested with a stress test)

By the way, in the stress test the fans went all the way down to 2800rpm and then the machine gets really loud. However, I have not yet been able to test any games or other programmes to see whether they can torment the processor as much as the stress test. So I can't say yet whether the PC will run quietly or not.

I hope I was able to help. :)
