The layout of the AB9 Pro is serviceable and I would hesitate to call it good because there are some problem areas. First is the location of the ATA-133 EIDE port. The port is located between the legacy PCI slots and the newer PCIe x1 slots. 2 additional SATA ports are right above that slot, and are therefore misplaced as well. Like ASUS, abit has placed a SATA port near the top of the expansion slots near the backplane of the motherboard. I have never liked that, and since this seems to be a continuing trend for motherboard manufacturers I can’t complain too much about it, though I still don’t like it. The floppy port is as usual for abit, at the very bottom edge of the board, directly beneath the PCI slots.
