Mount the fan and CPU after the board is supported in the case! Newer boards have circuitry running on multiple levels within the board itself. Kind of like multiple boards laminated together. You could flex the board and cause damage to the internal circuits. Boards also have components mounted top and bottom so by laying the board on a surface you could damage components from the pressure applied on the board for installation. The mounting points in the case are positioned for maximum support on the board.

ESD is still overrated. ESD products are a waste of your money.

Fryon, while YOU feel ESD is "OVERATED" that's fine when working on YOUR own stuff. I've worked for three electronics companies and have been "Trained" in ESD proceedures. Most damage done is not even visible to the eye. Now, if these companies thought it a good idea to train people in ESD, then I would think (my opinion) that it's not a waste of time and money, as some of the processes can be quite expensive. This is so they can get their product to you, so you can fry it!
