Woo! Run two HD4870s in Crossfire in microATX formfactor:

My biggest complaint in the past is that the mATX format is overlooked in the mid to hi-end of the spectrum. It may be smaller, but if you build in GbE, eSATA, and good audio, you don’t necessarily need all those darn PCI/PCIe slots.
Although I still dislike DFI as a brand (their reliability isn’t up to the standard of Asus, MSI, or Gigabyte, as far as I’m concerned), this is definitely a step in the right direction.
