It's a board design that's the same width as mATX but the same height as ITX. Sure, it comes with a decent number of M.2 slots for SSDs, but there's only one PCI Express slot. The latter is also an mATX board, with two PCIe and three M.2 slots. Coming back to the Maxsun YTX, the one thing that it does have going for it is that it's a 'rear-plug' layout, i.e. However, it's not enough to make me choose the YTX over any other mATX or ITX Z790/B760 motherboard.
