I have this monitor. My cabinet is 27" wide between the two large sides (I used 3/4" MDF so the total width is 28.5"). I made a 2x4 rectangular frame to slide the monitor into, and it fit just perfectly on the sides. So although the total width might be larger than 24", it will slide into a wooden frame that is exactly 24" (27" - 1.5" - 1.5").
