You can also get a Mediator ZIV setup. Then you will have 4 PCI slots like the Mediator LT, as well as 5 Zorro slots. The Zorro slot can be useful for a Kickflash card or Vlab cards for instance, and the busboard will have a connector for a PowerFlyer ZIV. Doubt the PowerFlyer ZIV is faster than the PowerFlyer MK3 though.
