This one has a bit more horsepower than that. No, no, NO. I don't mean recreate the old setup with the old software. I mean use the exact same bootdrive as you're using now and the exact same setup ! It's linux, you know, not windows. You can, in most all cases, just change hardware without any changes. The exception being if you have a kernel that is optimized for a certain cpu. But even then, a new kernel is compiled easily, seen as you have already done that anyway. So the question is: what happens if you ONLY swap the motherboard but leave all else in place (controllers, disks and linux bootdrive) P.S. I'd appreciate it if you reply to the list instead of to me directly.
