Type your motherboard's full model name into the search bar and press Enter.

"MIR" stood for "Motherboard Infrared," and the bracket could provide , a PS/2 mouse port , and an IrDA-compliant infrared transceiver port. Over time, ASUS produced several revisions of this bracket, with Rev. 1.11 being one of the most common. Many variations exist, from fully populated ones with all ports to simpler ones featuring only the two USB ports.

Look for the model name printed directly on the motherboard (e.g., ASUS P2B, P3B-F, CUV4X, A7V ). If you have the original motherboard the bracket came from, use that model. Otherwise, if you are adding it to a different retro PC, use that motherboard's model for your search.
