Max. Length of graphics card in enclosure: 300 mm
Graphics card length: 32.90 cm
According to the specifications, this is not possible. The enclosure does not have a hard disk cage that could be removed. So I don't think it will work with the card. As far as I know, the 3070s in black can only be used with this card: ASUS GeForce Dual RTX 3070 O8G or ASUS GeForce Dual RTX 3070 8G. Of course, there are also the ones from Zotac and MSI, but not in black.
