Has anyone tried them? I'm worry about their quality. Currently I'm using intel nics. But we are about to deploy a new firewall... and I just saw Supermicro released their new products - 5014C-MFB. Its 1u blade server with intel chipset board but Broadcom based NICs. I like their design, it is just what I'm looking for.

do a search for 5014

you will find the thread '2.4Ghz CPU and up'
