Pro: System worked right out of the box even though I installed blu-ray vs straight DVD, and added 4port USB 3 CardCon: On board nic didn't work so they install 1 port nic card. That would have cost a star.  Received unit on 6/29  and it's 7/22.  Nic card died.  That's the second star.  Faster to just replace nic.  I'll get a 2 port PCI vs a 1 port  PCIe.
