I built one about a year ago and it's been great. At that point they didn't include a lot of the stuff they do now, so my SB/CW2, nevermore, chamber LEDs, etc. were sourced separately and I didn't use most of what they provided for the hot end
I did the dragon HF, my kit came with whatever was before stealthburner and I bought an upgrade kit from 3dwest and went straight to that, so I never used the formbot fans and motor
