Need motherboard for home fileserver

Hi!

I need a motherboard for home fileserver with ZFS (but it'll do some
more jobs like massive ports builds and possibly video encoding),
but I'm really confused with which chipsets are fully supported, so I
descided to write here.

Requirements:
- 4 SATA II channels
- Gigabit ethernet
- Decent sound (it'll also work as media player)
- Dualcore CPU support
- Onboard video (machine is planned to be headless, so I don't want to
  bother with PCI or whatever video card)

http://www.freebsd.org/platforms/amd64/motherboards.html could be
useful, but it's outdated, so lists of:
- working chipsets with SATA II support
- working onboard GigE NICs
- working onboard sound chips

would be useful too.
