What's interesting about this is system is that it is a good illustration that there's a lot more expense and hassle than selecting the motherboard.
While the RPI might only be $35, you also have to buy a SD card ($10-12) power supplies, cables, boxes or mounting hardware, not to mention a network switch, etc. When you are looking at rock bottom price points, small things like the cost of the plug strip you plug it all into can be a significant fraction of the total. If you're making a cluster out of $1000-2000 nodes in a rack, you can ignore things like the network cable or power cord cost, because they're in the $1-2 range, but if your computer costs $30, then a $1 network cable is a 3% increase in price.
All of that might actually equal or exceed the cost of the processor.
You might be better off getting a stack of inexpensive netbooks or low end PCs.. A bit of casual googling shows that there are quite a few netbooks out there in the under $100 category (odd brands, it is true) (heck, I found one place offering refurbished netbooks for $45 each.. ) Move up to the $150-200 price range and there's literally hundreds of major brand units available.

Note: that is not the cluster called Iridis (also located there) :D
