Liquid cooling is then no option for you I take? :-)
Overclockers like to use it...

Cooling is not the problem, there are very good air coolers that will do
the job. The issue is BIOS support for overclocking which allows you to
control the clock rate, DDR clock rate, and voltages. Desktop
motherboards generally have these features, server motherboards mostly
don't. Overclocking is a selling feature for desktop motherboards, it
isn't for servers. However some server motherboards have included some
overclocking features, probably because the BIOS codes are basically the
same as for the desktops and the engineers developing the server
motherboards need to be able to tweak the same parameters anyway. The
decision to enable those features in a shipping BIOS is a subjective one
so some manufacturers may choose to do it on the grounds that it doesn't
cost them anything and that it might give them some selling advantage,
and others may choose not to because it could effect their reputation for
reliability. What I was asking was if anyone knew of a server motherboard
that supports the 45nm Xeons and was overclockable. As I've said earlier
what I'm really interested in is 16G of memory. A desktop board that
could use registered DIMMs would satisfy my needs. The availability of
4G unbuffered DIMMs would also satisfy my needs.
