CASE: Aerocool bolt

MAINBOARD:

Gigabyte B550 Aorus Elite

RAM: Crucial Ballistix 2x8gb 3200MHz

Power supply: Enermax Revolution Df 750W

SSD: Kingston a2000 m.2 1tb

CPU cooler: Arctic Frezzer 34 Esports Duo

(I want to have the pc on 1080 240fps in Fortnite on comp settings

second question:

do you know where you can get a ryzen 7 5800x

System looks good in itself.

For the RAM I would go to 3600 MHz.

And you just have to be aware that arctic and aerocool are really budget manufacturers.

I would rather go for a BeQuiet Pure Base 500 DX and e.g. Nen Dark Rock CPU cooler.

Quite overpowered for Fortnite, but good for other games, but not in full HD but more towards 4k, WQHD 144HZ. With Full HD, a 800 Euro PC is enough if you know how to invest the money.
