Although this is a duplicate thread ; that's ok, due to the last misunderstanding. 
... I don't think there will be much interest in this topic; primarily because the legacy ISA|PCI towers ( with the exception of gaming towers ) are pretty much not being used today. I have not powered up any of my legacy towers ( museum pieces ) in over 2 years.
The most compact clusters ( IMHO ) so far ( see malfunction_gk ) on this forum are constructed using distributed DC switching power supply ( at the bottom , or at the back ) filtered to each board in a stack with a speed controlled brushless fan blowing across all boards. A five to seven board cluster can easily be fit inside an 8-9 inch cube with relative skills and minimum expense.
On the other hand; the idea of placing each pine board as a riser card on a base board to handle power distribution and ethernet switch/ that is interesting; particularly if the board ( DIY ) could be downloaded from the net ! Most of the prototype clusters so far have been time consuming projects and hand-wired nightmares; although beautiful and highly satisfying.
On the same hand; placing the entire pine board as one of many riser boards on a base board doesn't make much sense taking into account the sopine modules which ware now available. The ultimate cluster base board would be ( again for power distribution and ethernet switch ) a host for multiple sodimm sockets ( 5 - 7 ) so that the cluseter is a cluster of sopine modules, not a cluster of pine boards !
