Those screws in the cover are a red herring, they do nothing. Just get all of the screws out of the side of the case, then lift up the black "clip" at the rear of the case and push forward.
Hi All, I've just got one of these bad boys, How do I open the case? I've been searching from Viglen & XMA manuals for the micro pc, but no joy. Any guidance will be welcomed. Thanks
