Any thought's on this build?

ASUS - Prime X570-Pro AM4 ATX AMD Motherboard,
G.Skill - Trident Z RGB 16GB (2 x 8GB) DDR4-3200 PC4-25600 CL16 Dual Channel Desktop Memory Kit F4-320016D-16GTZR - Black,

PERIPHERALS,
Cooler Master - Devastator 3 Gaming Combo with RGB Keyboard and Mouse,

All this is for 2,078.89+ 200.00 for the build, and another 300 probably for an actual warranty.

2,578.89  for all of this. But I don't know why the cost is so low.
(Also, I wouldn't have to go online for this)
