Blackminer F1 fpga miner does look and operate similar to most asic miners including Baikal and Innosilicon ones.  They all look and operate similarly for good reason, it's a form factor that works for readily available 120mm fans, and the ethernet/remote setup works well.  The blackminer guys have nothing to do with any of the asic companies.  They are nice guys and have even offered to open up their hardware for other developers, although most of the other fpga developers are far too busy at the moment.  I know several people with F1's in hand and they are all happy.  Technically I'm competing against them with my own software but the competition is friendly.
