A thread on building my new PC for flight simulation.

Step one: get all the components. My parts list: https://uk.pcpartpicker.com/list/fY2yVc
Step 2: update the BIOS to support Ryzen 5000 series (Vermeer) using a USB stick and Gigabyte Q_FLASH capability.
Step 3: Installing Power Supply Unit (PSU). I turned the fan downside because there was air exit grid on the case floor.
Step 4: Take the motherboard. Install DIMM memory slots. I installed them into the recommended slots to take advantage of the double channel to CPU.
Step 5: Unscrew existing CPU fan support and install the one provided by Cooler Master Hyper EVO 212.
Step 7: Assemble CPU cooler, apply thermal paste to the CPU and screw everything tight. Don't forget to connect the fan connector to the motherboard.
Step 9: Connect motherboard power cables (1 wide and 1 smaller). The smaller one took a lot of finger twisting. I should have connected them prior to fastening the board to the case.
Step 9: Insert M.2 SSD into its slot and fasten the supporting screw. This particular M.2 slot is directly connected to the CPU in my motherboard.
Step 10: Remove 2 expansion bay lids and install RTX 3060Ti graphics card into the PCIe slot. Also, connect the PCIe power to the card.
Step 11: Install SATA HDD in its bay (it took me a while to find how). Connect the SATA cable to the board. (I forgot to connect the SATA power cable
, I did it when everything was assembled)

Step 12: Everything looks fine. Connect the power cord and prepare a Windows USB installation media (I used Rufus https://rufus.ie/ )
Lessons learned:
- don't overestimate your ability with the fingers to snap everything in place. It takes TIME.

Total cost of the PC: 1165 EUR
