My current Core2 is overclocked and it's been completely reliable. I've
been running it 24/7 for about 15 months without an issue. My server
room is air conditioned in the summer and in the winter I keep the heat
down to 60 so I don't have to worry about running in a hot room. My
Core2 is using stock Intel cooling, I plan on using a heavy duty cooler
like the Zalman 9700 in the next box which should allow me to get
another .5GHz.

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

With my Core2 system I used sys_basher to find it's breaking point,
then I backed off by about 15%. I also underclocked the memory system,
the RAMS are DDR2800 but I'm running them at 600 which gives the memory
system plenty of margin.

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.
