I'm really happy with my 2200G. After hurricane Maria I spent around 7 months without electricity. I'm not sure what the hell happened to my Asrock Z77 pro 4. The only thing I can think was something got short from the high humidity/corrosion/whatever since I wasn't going to use my PC on a power...
Your idea of using slides to pull or pull the monitors is amazing. I've been looking for a long time for something like this.
What's the length of those slides fully extended and the weight capacity?
Great Job!
