Dan case style cases seem pretty common these days... yet none of them offer even two USB-A ports.
You have to understand that, for the great majority, front panel connectors in an sff case don't make much sense.
The need to have front panel connectors in cases arised from the relative ease of access to the front of the case when compared to the back. That doesn't apply that much to sff cases.
Plus, the IO in most modern motherboards is plenty enough for most people. And even if it isn't enough, you can just buy a USB hub, which, if positioned right, is more practical and accessible than a front panel USB connector could ever be.
So you're avoiding the mess of cables that comes with front panel connectors (specially the bulky USB 3.0 connector), which is extra important in an sff case, where things are most likely already cramped enough, and what you're giving away is something that almost nobody really needs in the first place. On top of that, it seems that most of us prefer the clean look of a front panel with no connectors anyway.
So you should be glad about the few good and tiny cases that have any front panel connectors at all, because to me that isn't much more than a leftover feature from big cases, much like men's nipples.
