Huh. I do plan on doing some serious modding, as I'm liking the case more and more. Modding's my thing.
Yeah, I was looking this up and it does seem the XPS has a special ATX motherboard in it, which is mildly annoying. But oh well. Speaking of serious modding, I'm looking at some case internal designs on the newegg.com and I came across a case that can house a mini-ITX and standard ATX motherboards in tandem and it made me remind myself of an idea I had two years ago when I was remodding my current Dell Dimension case: putting an Xbox 360's internals into the case.
Seeing as the XPS 600 is a larger case than mine, it actually seems possible.... That way, I can have good cooling and won't have to have a separate console and can just have it within my PC case. Nice and clean and minimalist. Much like the Windows 8!
