I'm just wondering what type of header does the Antec DP301M ARGB connector have and if it's compatible with the MSI B450m Bazooka Plus. And if not what's the best mATX case for budget builds?
Most likely a 3-Pin ARGB Connector, and no the the B450m Bazooka Plus will not support than 3-Pin ARGB Cable. The motherboard only has 2 5050 RGB Connectors and not a ARGB Connector. If you want RGB in your system, then I would recommend either the Phanteks P300, P350x, P400S. They are decent budget wise, and have decent airflow compared to other cheap cases. (Also, you don't need any ARGB Connector, you can just power it by SATA and then control the RGB using the case buttons)
