I have decided to take the plunge and give up with this control box, as much as everyone have been helpful I'm just so out of my comfort zone with my lack of knowledge, it is easier to just buy a pre-spec'd box and assemble myself. I have no problem what so ever putting things together, its just going to take a bit of time learning what each part of a box/cnc setup does, going to be a steep learning curve but a fun one.

I will start a build thread for anyone interested on how I get on with certain modifications I am making (adding limit switches, new spindle install, extraction system, custom bed, dust barriers, etc)
