To potential buyers:
The motherboard is NOT Ryzen 5xxx ready. In other words, if you want to use it with 5600x/5800x, etc., you need to first perform a BIOS update.
Personally, since I had never flashed a motherboard without a CPU/RAM before, I was a bit anxious, but the process is very simple.
1) Connect a USB flash drive (preferably up to 32gb, not more) and format it to FAT32 (Default), leaving the allocation unit size as it is (16 kilobytes) (any files inside will be lost).
2) Go to the motherboard's website -> support -> downloads -> BIOS category -> download the F10 file.
3) Extract the folder that you downloaded with the 4 files directly onto the USB stick (either by copy-pasting after extracting) and look for the file A520AOEL.F10. Rename this specific file to GIGABYTE.bin (you can leave the other files readme/efiflash.exe inside the USB stick, they won't bother us). Safely remove the USB stick and it's ready.
4) Take the motherboard and connect ONLY the 24-pin and 8-pin CPU connectors, without any hardware on top. Place the USB stick in the TOP LEFT position, labeled BIOS and colored blue.
5) Turn on/connect the power supply and press the QFLASH button for 2 seconds, located to the right of the 24-pin connector. An LED will start blinking and after a while, the fan on the power supply will start running. After 3-4 minutes, the LED will turn off and the power supply fan will stop.
6) Remove the power supply, take out the USB stick, and the motherboard is updated and ready to accept Ryzen 5000 series.

The process, although a bit nerve-wracking for someone doing it for the first time, is quite simple and anyone can do it. You can find a detailed video here: [link to YouTube video]

Now, as for the motherboard itself, it seems to be of good quality. It worked fine with the 5600x without any issues, and at a glance while using it for regular tasks, the temperatures and voltage on the motherboard are running at normal levels.

If you're not interested in overclocking the processor, don't plan on using more than 2 SSD/HDD, and want a motherboard with decent VRM, pre-installed I/O shield, a large number of USB ports, and a slightly more aesthetically pleasing design with all the necessary connectors (3 case fans, 2 addressable RGB, etc.), it is a solid choice (worth the price compared to cheaper B550 motherboards).

-The BIOS is a bit ugly, but in A520, you don't have many options, so it doesn't matter.
-XMP ran smoothly and without any issues with Corsair Vengeance RGB Pro.
-The RGB fusion doesn't offer many options, but it seems functional.
-The motherboard only has LED lighting at the bottom right where it says Aorus.
-During installation, remove the rear fan of the case beforehand because the heatsink above the I/O shield is large and will make it difficult. Personally, in the Dx500 case, which has 140mm fans, I couldn't install it without removing them.
-A negative aspect is that it comes in a plain box, without extra packaging or being sealed, so it would be good to check if it's a used/returned item.

If any issues arise or for any updates, I will inform you.
