Is this a good price?

I just bought a Pc for 400€ with the following hardware(no cpu):

Corsair Obsidian Series™ 750D Big-Tower-case, black - Corsair Lighting Node Pro Set, RGB-LED-stripes - Zotac Gaming NVIDIA GeForce RTX 2080 AMP (8 GB GDDDR6, 256bit, Boost-Takt 1830 MHz, 14 Ghz) - Power Adapter be quiet! STRAIGHT POWER 10 800 W - Gigabyte GA-Z97-HD3 Mainboard - 1 TB HDD hard disk - 500 GB SSD hard disk(Samsung 850 EVO)

Is it a good price?
