With this mobo and the previous mobos, the built in network was always
messing up.  On my first rig some 20 years ago, it was horrible. 
Reminded me of a winmodem I've read about.  I think the position of Mars
had more to do with when it would work or not.  It was mostly not on the
first puter.  The one before current puter was better but I still never
knew what to expect with it.  My current system would work for several
days but then would start acting strange.  To be honest, it could be
hardware, it could be the drivers.  Point is, I couldn't depend on
either one.  So, I bought a well supported card, installed it, enabled
it in the kernel and it has been rock solid ever since.  As a matter of
fact, the card I'm currently using was in my previous puter and possibly
the one before that.  When I built this puter, I moved the card over to
this system.  That card is pretty old but I have never had problems with
it at all.

I think the last time I was installing a SATA card, my video card was a
little thick.  Between the card itself and the heat sink for the chips,
it was to close for a card close to it, even if one ignores the heat
problem which shouldn't be much given my case fans and the whimpy video
card.  ;-)  I have a Cooler Master HAF-932 case with those large fans.

I ordered the card but I'm going to test the built in network shortly. 
All I have to do is unplug cable from current card and plug into built
in port.  Once I start that network, good to go.  If it works, great. 
I'll have the card as a back up.  If it doesn't, card it is. 

BTW, I found a good deal on a 8TB hard drive and bought it.  The store
had Unix in the name so obviously I had to buy from there.  ROFL  So,
network card and hard drive on the way. 

Thanks to all for the info.  When I test the built in, I'll post back
how well it's working.  Just for confirmation.  :-D
