Wow, sounds like an awesome build! Makes mine look like a children's toy haha. But hey, gotta ask, isn't that much storage overkill unless you're hoarding like every movie ever made in BluRay quality? Just curious about your use case, share some details!

Nova Launcher is a dope choice, been using it for years myself. For the custom look, also consider KWGT for that widget customization. You can create some sweet unique designs. And you're spot on with Poweramp, nothing beats that EQ.
