Cons posted on newegg about the 690-II that are worth checking out.
Cons: External USB, SATA, and sound ports are not grounded. Mine builds up static and my system resets always at the wrong time. It acts as if the reset button has been pressed. I disconnected the reset from the mother board just in case, no better. I swapped everything out from power supply to motherboard to memory and video card, same problem.
Cons: Unfortunately I have received a case that has the same problems with the front usb ports shutting down the computer any time you try to plug something into it. At first I thought I could live without them and just use the back ports. So I taped off the front ones to avoid using them by accident. Now, as another customer has mentioned previously, any time I have any sort of static built up and touch the case ANYWHERE it shuts down the computer and causes a problem with my motherboard where I have to go back into the bios and re-activate some of my cores because the static charge makes it think it was a failed overclock and automatically shuts off some cores (scary) and I DON'T OVERCLOCK ANYTHING. This case has terrible grounding issues. Extreme disappointment with it now. From what I have read there is NO way to resolve this problem. Will RMA and purchase another brand case unless Cooler Master can provide a fix or a resolution before I RMA it.
