You can retrofit a gpu without changing the mainboard.

The one on the left is for fan control. Here, the ventilation can be increased or reduced depending on the load. The one on the right is the reset button, which should only be used if the PC is frozen and can no longer be controlled :)

No, it does not have to. But as with any PC, you should clean all fans thoroughly on a regular basis.

A little, but you have used components that are far too expensive. A 650-750 watt power supply is sufficient, Windows 10 Home for 107.- is also sufficient, Samsung Evo SSD is cheaper and fast enough, there are cheaper mainboards for approx. 250.-, HDD is more designed for servers, thus hardly fast and intended for gaming. recommend Western Digital BLACK edition. Otherwise, CPU and GPU are good, except the Intel 6500-6700s would be a bit cheaper.
