I do not know a lot about Heatbit. They cost $1200, right? And you cannot change your mining pool, it uses Nicehash, right? You can buy a used S9 for $150 and have 100% full control. How loud is your Heatbit at 14TH/s? My S9's are underclocked at 10Th/s and aren't loud at all. The nice thing about Heatbit is that it looks great, like you said. S9's are "ugly" unless you get a nice 3D printed case for it.
