I bought one of those ASrock C2750D4I boards and had trouble with FreeNAS crashing whenever disks on the Marvell SATA controller was under heavy load. I had to RMA it twice... I had already wasted so much time I eventually gave up and used only the Intel ports... and then it finally just died...
They are successful because of the exclusives they have (mario ect) games they come out with are fun and have a great story line and are just enjoyable to play even if they aren't the best graphics, latest hardware, non hd ect.
