Some of you may be wanting to think about creating your own super computer out of the new Mac Mini. Obviously you will have some consideration as to model and connection between them. But let me give you some calculations. Lets just say you want to make a stack of Mac Mini's in your apartment. My apartment has what appears to be 9' or so ceilings. So a single stack would be.... 54 Mac Mini's Maybe you want to use xSan to network the drives, giving you... 2.16 TeraBytes of data and 4.32 TB for the highends. All this would cost you less than $27,000 ($32,346 High) Hmm, thats impressive, but lets say that you want to have as many computers as the "Big Mac" 1100 Mac Mini's would mean just 20 stacks with 20 MM's left over. If we put it into a fictional 9'x9'x9' cube room, then the 1100MM's will only occupy less than 7.4% of that rooms volume. And give you 44TB storage (88TB high) for less than $550,000 ($660,000 high). Obviously for a proc. equivalent to the Big Mac, (2200 G5s) we can just double the specs... 2200 Mac Mini's 14.8% of our cube room 88TB (176TB high) $1.1Million ($1.32 Million) What would it take to fill our 9' cubic room?? Well it would take 14,906 Mini Micro Mac's (assuming the remaining 155 cubic inches was all it took for the powersupplies, not super realisitc) 14,906 Mac Mini's ~600TB (~1.2 ExaByte 1200TB Highend) $7.5 Million ($8.9 Million Highend) Comepare that to the cost of the Big Mac @ $5.2Million. Think of the folding that could be done. Obviously you would either need to get a firewire or USB2.0 low latency network, or distribute your work so that a very small chunk of data requires a large amount of clock cycles.
