I came across these pics on VR-zones forums compares all of these cases.

I felt I should post these as it is very hard to differentiate between the 3, size wise. I was shocked that even after measuring, numbers are deceiving.

So here we go:

SG01W vs SG07


SG05 vs SG07





Thanks to dr_disciple for posting these.

After seeing this, I went from wanting the SG05 for its compactness to the SG07 since upgrading to a 450w PSU only changes the difference in cost to $25, which for me doesn't matter and I'd rather have 600w and room for longer cards and bigger heat sinks w/ 25mm or 38mm thick fans!
