Great review.
I'm not familiarized with Biostar's products, since the only thing I see from them here are some old GeForces, but the quality always seemed a bit dubious.
But your review helped me rethink about that. It's a bit spartan with the connectors, yes, but I see a good layout in the expansion slots and the rest of the features remind me of ASRock. All the needed goods and features are there, not extra glitter.
The odd size immediately gave me the idea for a LANRig using those old Pentium 2/3 chassis, which are very crowded by today's standards.
I'm thinking of a board like this plus a 2500K, 8GB of RAM, a HD 6870x2 and a GeForce for PhysX would be a good configuration.
