After finding I had lost Watercooler grommet(one of the two larger ones located at the rear of the case), I thougt it best to get another one to keep the airflow trim. Having e-mailed CoolerMaster twice(european first and then states) I got a response.........after waiting a week, having heard nothing, so contacted there U.S. branch. Finally someone got back to me the following day. Joy of joys!.... I was hoping they'd offer to send one free of charge.......but, au contraire, only to be shafted for five pound odd for two grommets (which they must have 'shed loads' of and which cost all of tuppence to make.........so yeah, .....GREAT SERVICE and COMPETITIVELY priced....NOT!!!!!!!
I mislaid the top cover for Cooler Master case and could not find the correct one over the internet. I contacted 'Cooler Master' direct and had excellent help and advice. It was a part they do not normally stock as a replacement but with their help managed to send me one. It is exactly what I wanted and the service and speed of delivery was really good. Cant recommend their customer service high enough. Excellent!!!
