The case supports mainboards in E-ATX format with a maximum width of 280 mm, ATX, mATX and Mini-ITX. The ASUS Rog Maximus Z890 Hero Btf is an E-ATX mainboard that usually measures up to 305 mm wide, which is often the standard size for E-ATX. Since the case only supports E-ATX up to 280 mm width, it is very likely that the ASUS Rog Maximus Z890 Hero Btf will not fit into this case.

To summarise: An E-ATX format motherboard with a width over 280 mm cannot be installed in the case. The ASUS Rog Maximus Z890 Hero Btf is an E-ATX board that is probably wider than 280 mm, so it cannot be installed.
