I don't under stand why you think you'd need bay adapters then mate ??
That enthoo will hold 8 drives as standard.
Anyway away from that consider the deepcool kendomen.

I'll be honest, I don't see a massive issue with your ostrog for cables , there's a fairly deep tray for cable management on it??
The kendomen does seat drive power/data connectors away from the open side panel though so you can route behind the board completely & have no drive cables in view at all.
