Unless you use excessive physcial force to bash it together, there is very little you can do wrong when assembling it.
You mean the universal method of "smacking it to fix it" doesn't work here? Darnit.
This also means it'll be much easier to modify in the future though, which is an enormous plus for me. What the heck, this is the best option I've had so far, and I don't to compromise on anything, while also keeping a nice price. Add maybe 200$ for the screen, keyboard and mouse though, and this is sounding cheap but really effective.
