seeking ideas for nano cabinet organizer

[Ballyhoo]

so I got the Red Seq nano XL and the cabinet is just one open space with no organization. Can anybody think of any organizer that might fit inside here with different shelves and things? Really appreciated.
also, on a separate note, the waterline is slightly more high on the forward end, and I have the whole unit sitting on a reef mat

I have something similar and I was able to measure and find some of those white plastic drawers for supplies.. either that or you could always DIY some matching black shelving/drawers.

Sorry, no help on the reef mat, hoping someone with this system can help ya out there.
