Anybody do sheet metal work? I am wondering about whether the way to do a mod I plan is to have a front panel made which has cut outs for fans as I want them. eg. Define R6 takes 2x140 or 3x120 in front. It has sufficient space (removing Optical bay) to have 2x140+1x120 (I'd have it full of HDDs which need cooling). So probably make up a mount for 140-120-140 for the front.. But I'd need to find somewhere to get a sheet of metal cut to spec.... ANy ideas?
