Huli has gone away, and I don't know when he will be coming back. I hope he does, but it seems we have lost another around here.
Update ... everything seems to be working fine. Even got it to boot and run with 4GB of memory, so another hurdle passed. Gotta spend some serious time on cable management and water cooling the NB and then the GPU. But, my goal this time is a working system. Looks are definitely not a consideration.
