I have a bad back and there's no way I'm going to sit at my table while putting this build together; I'm much more comfortable sitting cross-legged. I've got the box from my 43" monitor I can put everything on; think that'll be ok for antistatic control? I mean I may move a bit on the bed but not much. I've done work on my computers before and without precautions never had any problems, but this is a complete build so figured I'd ask?
