Hello, I want to replace my motherboard on my HP m9300t mainly because I want an i5, faster RAM and a better video card. The stock MB will not allow me to use a double-width video card without losing a PCI-e slot and I need them both as I have two digital tuner cards I use for Windows Media Center. The selection of m-ATX MBs leaves little choice. The tuner cards are supposed to work with x1-x8 slots. Does this mean they can plug into the longer PCI-e slots or must they be the shorter x1-style slots? If they can use the longer slots I have a much wider choice of MB to look at. Thanks.
