You've got some spelling errors, for example in §1.3 (correction bold):
In a sense, we all do! Anybody who is willing to participate and support the bitcoin community is a controlling interest.
Furthermore, in §4.1 you state the necessity for Computer Mouse, Monitor, Keyboard and a monitor cable. However, you don't really need these, since modern boards usually support network booting, so you can install pretty much any linux distro via ssh. A beginner probably won't be able to do this without help, but since additional hardware costs money, and learning this stuff is pretty useful, you should include a remote setup tutorial. Also since the user reading your tutorial has most likely internet access, he already might have these components, or very likely could just install the mining system on the USB-stick and continue configuring and administrating the rig via ssh once the stick is bootable.
