Inside - details Pt 2
At the back of the chassis are the blue clips that hold cards in place in the expansion slots.
The downside with these retention mechanisms is that they don't work for dual-slot GPU cards - and that applied to us, as our 2900XT required screws to hold it securely in place.
Alongside the motherboard area are various cables pre-fitted inside the 690. There are plenty of them, too, so it's good to see that Cooler Master has provided clips to keep things moderately tidy.
