people would buy that and use it for anything but xeon and ecc ram????
there are reviews from customers who bought a server board and stuffed
it
with i7 and non ecc ram!?!!

I have no need to PCIX slots (home system, and, besides, most SAS
controllers
are pci express based these days anyway)

The idea was to use core duo/quad on the cheap instead of xeons in X48

Even if they were which i don't believe they are i would not want to
test
the socket compatibility by stuffing a desktop cpu into a server board
and vice versa.
Though judging by supermicro xeon x58 board reviews there is no
shortage of people
who would. Is not a P55 based board a much cheaper route for those
folk?
