The ATX motherboard has one of the larger motherboard form factors, with dimensions around 305mm x 244 mm.

microBTX is approximately 264mm x 267mm,
NLX is approximately 254mm x 228mm,
and microATX is approximately 244mm x 244mm.

  1. The NLX looks like it has a larger footprint then the ATX. The NLX is longer but is less wide. I wonder why you chose the ATX to have a larger footpront over the NLX.

      1. On your your 602 video about motherboard form factor you have the dimensions for the NLX as 340x230mm and the ATX as 325x267mm.

        NLX = 340×230 = 78,200
        ATX = 305X244 = 74,420

        Is this a newer update then what is on that video?
        I know BTX was not one of the answers but it looks like that has the largest footprint of them all.

        Thank you for taking the time to answer these question.
