This RMA process is really dragging out. After quibbling with their rep for several days, I was finally given a link to a RMA submission form, which was ultra simple, and had to wait for 2 more days for a response. I got the RMA#, but no prepaid shipping label as promised, and it stated that they would either repair or replace the motherboard, as they deem fit. I did not order a new motherboard only to receive a used/repaired one instead.
To spare anyone from this type of headache, the name of this vendor is Imicros AKA SuperBiiz.com. This shall be my last transaction with them. I wish that I had ordered from TigerDirect, it would have cost $15 more, but considering the manner in which SuperBiiz does business, that would have been cheap. I not only lost time, but it appears that I lost both the 10% ebay coupon, plus the cost of return shipping.
