I have just completed a commission for some test benches to be built into custom desks.

Part of the challenge was getting a cohesive look between the tray and the IO section and making an ATX tray with a low profile IO section sit well alongside a E-ATX tray with full size IO section.

For me there could not be any compromise by providing anything less than a firm connection for PCI-e cards and so I devised a robust, but delicate looking treatment to the IO section which also allows for an easy swapping of components.
