Now, from what I gather from the thread is that the way to link them would be with the ethernet, that is bot bad, does anybody have an idea of how it could be done (the linking them and having them work as one computer) the screen and all that is not so hard to figure out, much less storage... but the linking them is the hardest part. Any ideas???
Use Ethernet. It may be a bottleneck, but not as much as anything else you build.
And then research something called OpenSSI.
