Considering the price and the limited run, I'd expect much more polish from the deliverables (and more of these as well).
E.g. The LED strips should have been fully tested, and pre-installed into the channels before shipping out.
I don't expect the strips to overhang the channel as well - they should all have been trimmed nicely to exact lengths and fitted with nice pigtails of exacting lengths to clip together.
There should also be cable retention clips (beefier than the 1000 pack stuff; maybe custom 3D printed?) or carved channels to fit/ route such loose ends/ IO cables across the board.
To me, these little details are what differentiate a high-end bespoke set from a FMCG.
Even with these changes, I'd expect a decent pump unit and possibly a Rad included given the price point as well as miscellaneous accessories like tygon tubing or hose lamps etc.
