The behavior is the same with high-end _servers_. The
difference in
price is justified by the fact that you get even better service and
assistance, and on site technicians to replace broken parts in 24
hours (or less, it depends on your contract).
Not quite. Servers also have server motherboards which apparently are much
higher quality hw and bios than consumer motherboards, such as "Security"
feature which requires password *after* a potentially malicious user has had
an option to trash your RAID array via BIOS raid menu (courtesy of ASUS).
