Hi,
I just got a used Cooler Master Quick Fire Rapid - Cherry MX Black. The price is cheap at 34 USD. But it's getting a lot of dust and rust on plate. On one hand, I need to simplify it and cure the rust. On the other hand, I'm not going to invest a lot of efforts and money to it.
There are some steps that I did:
+buy 02 bottle of paint (Blue River and Apple Green), some fine grained sandpapers, 1 liter of gasoline and 1 liter of alcohol 99%
+disassemble the switches
+clean the old paint with gasoline and alcohol 99%
+clean the rust with sandpaper 400 and 600
+paint the plate with blue river colour.
+replace the switches with Cherry MX blue.
+simplify the roof to cover only the controller
+paint the roof and bottom
+assemble switches
+put Filco Ninja keycaps to it
Total costs: + 15 USD
Definitely, it is not perfect but it is so much fun.
Here are some pictures eventually:

After using the keyboard at work for a while, I think Cherry MX Blue should be used for typing at home only because it has a lot of noise. That does not count the fact that I'm using ABS keycaps and the keyboard top has been removed.
Therefore, I mod it back to lubed Cherry MX Black (my favourite switch type).
This time, I used a different type of paint (higher roughness) with white-grey colour .
In conclusion, Cooler Master QFR is a good keyboard with low price.
It is worthy enough for modding with amazing results.
