Looks pretty much like the one in your first post.
All in all, not a bad deal
Dell is kind of infamous for using proprietary parts, custom shapes and the like that are difficult to fit in aftermarket configurations. I think I read somewhere that upgrading a CPU is next to impossible in some of these models, and I remember a few years back something about ATX pins from the PSU having a different pin out (looks like it fit, but turn it on and BAM- everything fried!).
I understand that all pre-built systems will be less modular than one from scractch, but from what I gather, Gateway is a bit more standardized in the parts they use than Dell. It also helps that Acer bought them, I think.
