They are a good company, but they are hardly the best, in my opinion, and I'd chose an ASUS, Gigabyte or ABIT over them any time.
I am anxious to see an ABIT BTX board... that may be the condition I need. I have high hopes for BTX config. As you can see in my sig, I am a "neat-lover" inside my case, and I beleive this new format will help for better looking cases.
There is hardly any need for full size BTX boards, in my opinion. Boards come so integrated nowadays, that not even I use a PCI slot, and have not seen many use more than two or three at most.
