the only big problems i can foresee are:
cpu cooling..your going to need a low profile cooler, and some good fans. i assume that case is mostly wood, so it wont disipate heat as well as something metal.
video card: because of the low profile of the case, you will probably have to use an agp card with a right angle riser board..but this will also cover your other pci slots..but a standard height card wouldnt fit anyway, so probably onboard audio.
power supply..i would go with a server ps something low profile like a 1U, and make sure its spec'd for atx.
this is a basic setup..it will probably vary depending on the size of your components.
