I agree the posted mail is most likely a scam. But the OP looks genuine, and these boards actually do exist (seen on other hardware review sites).
Not sure about user 'Biostar'. What makes you assume that the scammy mails were originated by him?
the user Biostar sent PMs to me and dropt asking if we would be interested in testing/reveiwing dev batch units, and included a list of specs and claims of the upcoming device.
I asked for proof that they are with Biostar, and have not received any yet. I was offhandedly asked if id be alright paying the shipping for free units (no price given).
Dropt reports very similar experience, albeit complemented by a fake email pretending to be from biostar but actually an email anonymising service. IIRC he was quoted an actual shipping price.
I suspect Biostar is indeed at work on a second generation board - the first one reviews well and is inline with other 110nm efficiency. A drop to 28nm and some redesigns for modularity would allow Biostar to make a good gen.2 in theory.
however, the username Biostar appears to be a scammer, looking for people who might pay shipping costs for a review unit. tread carefully
Same exact thing here, just no email.
