Finished building my Singa with 62g vintage blacks, 204 grade 0, brass plate, and GMK dolch.  
Keyboard quality is fantastic.  Everything fits very well together.  Only thing I dislike is the sound of the keyboard but that's okay since I'm enjoying typing on it thus far. 
What about the sound do you dislike, specifically? 
Also - any and all photos videos of the build and all angles are always appreciated! 
Yes, photos when I can get my hands on a nice camera  

, but to address your question, the bottom piece and the pcb is a very low clearance, so most of the sound isn't able to reverberate properly like on some other keyboards I own (Mech27, Duck Viper, even my Weaven).  The result is that the keyboard isn't very deep pitched.  I can mostly hear the clacking the keys, and the spacebar is extra loud as a result.  This could also be because of the brass plate that I am using.  
If I get my hands on some shelf liner, I'll be sure to put it under to see if the sound changes.
