They are higher because you need space for the PEG connector on the GPU. All the cases you're posting about are not high because the GPU will only be 1-4mm away from the sidepanel, which disallows the use of any GPU with a PEG connector, so anything stronger than a GTX 750Ti.
Additionally, all these full ATX cases you post are actually wider than something like the SG01, SG02, SG11 or SG12, all of which are pretty much the exact same layout as you posted, just as small as possible and designed for use with high-power GPUs.
That means that they appear to be even higher, they don't have that HiFi look on the front to them, but they are still smaller than the case you posted here.
If you could tell us what the problem with any of the Silverstone SG01, SG02, SG11 or SG12 is, we could maybe help you a bit easier to find a case the suits your needs.
If you really want to use this case, though you could modify the outer shell by adding more vent holes and you'd have to modify your GPU.
