Real good question..
Perhaps not directly an answer to your question..
So a couple of days ago i bought the Leopold FC660C topre keyboard because i love the Size..
And i own the FC660M with mx-clears.
There are a couple things on my mind i wish to share with you and of course anyone reading this post.
i tried the NovaTouch for a second standing in a store..
While a kid working there was hovering over me and my wife like a vulture..
He was apparently amassed by the price (being so high) and level of packaging, he also had no clue what a key-cap puller was.
Until my wife told him "That's a key-cap puller" hahahha

Can you imagine a girl that has no intrest in anything having to do with tech or keyboards telling someone that works at a computer store what a key-cap puller is for ?? dear god !!
But after reading this post and seeing earlier posts in regards to modding i Started to think about the potential of the NovaTouch..
According to a couple of people these rings really improve the feel and sound of the NovaTouch
help-f53/silencing-rings-for-topre-rf-or-hhkb-t10051.html
And there is a keycap set that is supposedly the best one to use with this keyboard..
"Signature Plastics SA profile Thick ABS"
Adding sum dampening material this keyboard could possibly be the greatest invention since sliced bread hahaha :ugeek:
In summary To mod this keyboard ..Would cost an additional;
$50 best Keycaps for this board
$65 Topre rings
$30 Silens material like VibraFlex mats to cut and stick to the inside of the case.
Total $145 on top of the Store Price..So if the NovaTouch were around $110 it would be ideal for a pimp up mod project like this.. Competing and surpassing the likes of RealForce And Leopold ..
Because one awesome thing about the NovaTouch is that you can use Stock Cherry mx caps..
I would even go so far an try to trow in a teensy to make if fully programable using a OpenSource solution provided by the guys from InputClub.. So no need for expensive R&D hahaha..
Well that's my view of this keyboard with great Potential.. Of course it would take a great deal of time and effort..
But it would be like modding your Case..
