Nothing wrong with that...

A desktop board?

Those usually have top-of-the-line devices (SATA, Net, sound) which are
not widely supported, or even stable.

I've seen (and sometimes built) several Intel Xeon 51xx systems that
work without problem with server boards.

If you're willing to pay for it, server boards will suit you better. For
example something like this:

The server version of Core 2, aka Xeon 51xx, works fine in both 32-bit
and 64-bit mode.
