Motherboard Replacement?

[OTRENOX]

Once again, I am making a post asking about tech stuff. 

 

Now, I am looking into a new motherboard for my: Inwin101 case, AMD Ryzen CPU, and AMD Radeon RX 580 GPU. 

Also 8x4 GB RAM modules.

 

Looking for a case that: 

> Supports my Case, CPU, and GPU

> Has 4 RAM slots

> Works with AMD CPU’s

> Has an OK I/O

 

Any suggestions?

 

(Budget: $100)
