My Anet A8 Plus was a "bit" of a pain to wire together, but overall, I would say not that hard, and it looked pretty comparable to that Tarantula when I started and now looks a bit like the user manual. There were no guides for how to neaten the wiring but they provide some cable organisers and cable ties, I'm pretty sure even a trained monkey could manage to make it look a little neater. I, too, sense NFI.
