A pretty simple AM4 build I did. Not looking to upgrade the GPU unless needed for now

Ryzen 5 1500X CPU
B450M MORTAR Motherboard
8GB DDR4 2400MHz Corsair Vengeance (cl14) Memory
GIGABYTE GTX 950 OC GPU
Patriot Burst 240GB SSD
Western Digital Green 1TB HDD (WD10-EAVS)
Corsair CX550M Power Supply
Corsair 88R Case

The 9900K competition has a ATX board, will upgrade to ATX case if I do actually win the competition lol
