Been comparing width measurement between R3 and R4 and something isn't right.
I'm guessing the 170mm CPU clearance is really 180mm
R4 is 24.6 wider than R3 but only 5mm more CPU clearance??? Okay, R4 is 8-13mm more behind mobo + 5mm so 13-18mm total width.. Where's the other 6.6-11.6mm
R3: 207.4mm width,165mm CPU clearance , 13-18mm behind motherboard. 178-183mm + 15mm (mobo, standoff, CPU socket) = 193-198mm + 10mm for sound dampening. and we have 208mm
R4: 232mm width, 170mm CPU clearance, 26mm behind motherboard. 196mm + 15mm (mobo, standoff, CPU socket) = 211mm + 10mm for sound dampening. and we have 221mm. Wheres the missing 11mm??
