In the following test I take a closer look at the BT-04B-U3 from Chieftec, a compact ITX case with handle and already installed SFX power supply.

German Version can be found here and here...
I considered the C7 and the L9i for a DAN A4 SFX v3 build. I didn't know which one I would prefer so I tried both. I'm sharing my findings in case it helps someone.
TL;DR: If you can tolerate the weird fan noise get the C7. Otherwise get the L9i but make a fan duct.
