Hey guys! I just got off the phone with an EVGA customer service rep, by the name of "Chris" and he said that normally modifying the graphics card housing would void the warranty, but he said that as long as its just like physical damage to the housing and its repairable/able to be replaced by their factory.... theyll charge like $30 or something he says, to replace the "modified" housing before they help you out with your RMA (say you RMA it with the modified housing).
I asked if this was just a "deal" that they do with people over the phone, and he says no... they do this for anyone and as long as its not like a physical damage like a screwdriver to the PCB and causes a scratch (ouch).... but INSTEAD, like something minimal like "i modified the housing to fit my waterblock in it".... they said thats not going to be a problem if you need to RMA your card. You just need to tell them ahead of time that you have the damaged/modified housing and theyll take the necessary steps.
So i think im going to start modding my graphics card housing to hide the H80i in it. Im sure it will look SUPER clean now
