I should have found this thread before I ordered, but I believe your website is misleading in regards to this height for the ITX5.
As quoted from the website:
Maximum height of motherboard with everything installed on it is: 2” 1/8 = 54mm
HDD: 1x2.5” HD and one 3.5" HD or two 2.5" HDs.
I read that to say that if I have a 2.5" and 3.5" hard drive installed, the maximum height of the motherboard with heatsink and cpu cooler is 2 1/8". I found out the hard way that this is not the case, as you have also stated in the part of your post that I quoted.
Your website does give the 1.5 inch height as the limit for the ITX7 case. According to your statement above, the height limit is the same for both, even though the website says differently.
Based on my measurements of the itx5, there appears to be a simple solution that I believe has to have been the design intent of the itx5 but was not implemented for some reason. The hard drive bracket in the itx5 is the exact same as the itx7 as far as I can tell from the pictures. What this means is that my itx5 bracket also has a large void (5/8") on top where a disc drive can be installed, even thought the case has no slot for such drive. It happens that this 5/8" space is the same as the height difference between the quoted 1.5" max cpu/hsf height limit listed for the itx7 vs. the 2 1/8" height limit quoted for the itx5. I believe that the hard drive bracket was meant to be flattened out on top, giving that additional 5/8" clearance to the cpu/hsf when a 3.5" hard drive is installed.
I'm going unbend and trim back some of the mounting flanges to see if I can make it work as I believe it was intended to. I'll post pictures if I'm successful.
I'm just posting this so others are aware, in its current form, there is zero benefit as to the internal height of the case with the itx5 vs. the itx7, contrary to what the website would lead you to believe.
