I normally have butter fingers to the max (my wife/co-developer did the actual physical work of putting the machine together for these reasons and neither of us remember seeing any short of control). Her immediate comment on the idea of drilling into it was something along the lines of not the smartest idea and one of the dumber ideas we have heard in a long time. > > On Fri, 2023-05-19 at 15:32 +0200, Tomek CEDRO wrote: > > These "RGB" fancy pancy devices usually have some sort of "RGB > > CONTROLLER" that is a separate device somewhere where cables come in > > Related to the word "usually" Google proves you wrong.

Every time I do a DIY there is also some part or an other that never quite fits/works/etc. since for the first time in the last 15 years (before then it was easier in general) I/we managed to do it with out this or one of us getting cut by something sharp on the case or other such incident I think the RGB fans are this DIY's "we should asked about X". > > I guess the situation is like this, Aryeh Friedman decided, before he > starts crying, since he already is aware about his worst case + 1 > situation, as a last resort to send a request to this list. > > The workarounds are drastic and risky.

The most practical solution we have come with is block the view somehow --=20 Aryeh M. Friedman, Lead Developer, http://www.PetiteCloud.org
