Still I'd be willing to bet we could find a way to reduce their performance impact if we put our thinking caps on. I totally agree on more EATX support though, especially since several of ATX cases seem so, so close to being able to do it as they are.
I will take the popular R5 and S as an example for grills as it seems to me to be the most up to date designs.Front:
both have already updated front intake with reduced grills compared to R4, although in the mesh filter you don't need so many horizontal line supports and on S not even so many vertical ones, especially when the supports are thick such as on the R5 filterBottom:
PSUs come with their own fan grill, there is no need for a grill on the bottom of a case really, no one can even see that and especially not after installing a PSU and a dust filter there, bottom fan and cage area grill can be useful for water coolers and moving cage to different position for those that use drive cages, still even those can be removed and cages screwed in at the 140mm fan holes along the edge, like so, I've kept on my R4 just in case. In progress pictures below.Warning: Spoiler! (Click to show)
it's more of an aesthetic question, with no fan the holes would be covered by the covers there are on R5/S, when fans are installed they would be completely open with no grill present, on the other hand people like to install custom grills on such visible areas anyway and the restriction from a radiator is already bad enough for the fans, adding spare wire grills would also work for those that want to protect their top fans from mishaps without impeding airflow muchRear:
it is not visible in most use cases and can be left open with no worries, again included spare wire grill should satisfy those that want it protected or visually enhanced
I'm sure wire grills don't have to be the standard ones, you can also design your own that please your design department
I remember wire grills being quite common long time ago as it was easier to make a big hole instead of stamping a mesh into sheet metal. Then the machines for stamping got common and everyone started stamping custom stamped grills with huge air restrictions. A shame really.
LED ring, I'm not sure if R5/S has this but I've moded my R4 to have blue and white LED one for power and the other for drive activity. Looks like this:
Personally I have both of these LEDs disabled in UEFI though
The white simply blinks when I start the PC and that's it for me, I find LEDs distracting especially blinking.Edited by JackCY - 7/15/16 at 6:22pm
