ECS = Elite Group. I consider them to be more of a value or budget board. I use them in almost any budget PC I build because of their cost <$50 with with onboard sound, video (Shared), LAN. I have never had any real problems with them, nothing more then the usual anyways.
They might have "Higher End" boards as well, but I've never used anything except their cheaper models. Not sure I would use one in a hight end game system for example but for those people that are just using office and checking email they should be fine.
