My DF-35, judging by your photos, is similar. The front ports and LEDs are un-marked; Spkr., Mic., HDD, you just have to guess. The extra plastic jail bars across the front bays must be left swung open or snapped off for your optical drive to be usable. I will say the cooling is very effective. The box reads, "Designed by Antec in California."
This resident of California says, I wish they tried a little harder. Not up to previous Antec standards.

I'm still waiting for a case to come along that outperforms the cooling of the Silverstone FT02 Fortress. I'm loving these new modular designs but realistically I can't see myself benefiting from them.

... its just that instead of IEC 320 C13 (the familiar "kettle plug"), it uses C19 which is designed for higher power applications (up to 16A).

Its not an issue in 230V countries, but the higher current rating will be necessary in 110V countries like the US.

HTH.
