It looks like the UD7 has increased spacing between slots. They have the same 7 slots as the UD3 taking up significantly more room….might give decent cooling even on air with cards side by side which has been a problem. Even an extra 0.5 cm gap between cards would sure help with cooling the two slot cards on air.

Never mind, that would be impossible since it couldn’t fit the case then…they are just starting one slot lower than on the UD3.
