Left to right it looks like a power supply, standard ITX motherboard and RME soundcard. You could build it for less than $1000.00.
One of my pet peeves, and I'm not picking on you specifically Frank, is that there is a lot of work involved beyond the raw parts cost. This involves many man-hours that have to be amortized across all the units. I don't work for free and neither do the people that developed the product.
Comparing raw hardware costs with a product with substantial R&D costs is a bit like saying you can buy all the components for a house for $25000. Sure, but what about everything else that goes into taking it from a collection of components to a finished product?
