The board is listed on the bitcoin hardware wiki. Complete with link to newegg.
Someone who wanted to get into bitcoin but might not know computers inside and out, would probably follow these suggestions to the letter, no?
There are only a few reasons I can think of why people return things, most often for compatibility reasons.
Anyways, I'm betting you got an open box from another bitcoiner who found the MB gave him the same problems and returned it. The newegg lab saw the board would post and put it back on the shelf without detailed testing.
