Hi folks,
I've been wanting to get my feet wet in SHA-256 mining as a hobby, so I went with the Raspberry Pi 3 with USB ASIC miners. I originally started within a $300 budget, but was able to spend only half that.

After getting a crash course in Debian/Raspian, everything is up and running! In hindsight, I didn't end up needing the microUSB cables because some came in with the Raspberry Pi kit, and the powered USB hub connects by USB 3.0. Oops. The RPi3 kit is pretty neat since it comes with some accessories and the NOOB, but I find that the case included to be a bit too wide to plug in the power cable without taking the RPi3 out of the case.
The "2pac" ASIC miners, at 125Hz, are cranking out about 13-15GH/s each but I hope to upgrade in the months to come.
