I have received it and came back for comment. This thing is expansive as hell, but it worth every single penny.
After assembled it, it looks as beautiful as the advertisement photo. Everyone deserved to have 1 piece of this art and I hope the price could drop to like $49.99 for everyone to have it. The whole thing is very well designed include the package, which you will receive a small size package, and after assembled the actual thing is actually quite big. The acrylic cutting is very accurate and flawless (you must follow their step or else it wouldn't fit). Also it is great that it does give you some redundant led and case clip in case any piece is dead on arrival or lost.
Also for any electronic project the most painful thing would be troubleshooting. For my case, after plug in all LED I thought it may need some troubleshooting, but no, it just worked flawlessly. The only bad thing is when during assemble, one of the base of led bend badly (on arrival, not done by me), and I have to bend it back and prey it not break.
Otherwise it is very simple to assemble. The most painful process is to tear the protective sticker on acrylic case, and to screw in the screws on very edge of case, the screw is non-magnetic and it is PITA to aim it at some depth in the case where the clip can drop easily before screw in.
