Mine isn't listed there.. likely an older model.. looking at their legacy stuff.. very similar to the LC04.
You are correct, about the tightness in there.. with a FULL more super powerful video card, which is very long, double witdth, etc.. you may run into space issues against the drives, depending on the layout.
I know on mine, the ODD, was on the CPU side, so likely wouldn't interfear with a video card, etc.
Going to a microATX over a ATX, etc.. wont change a lot, depending on the layout... I would think.
Usually your PCI-E slot, is the closest to the CPU etc.. which would fall in the same spot, weither a full or micro ATX.. so if its in the way on one, will be in the way or the other.
Going with a slimmer box.. you could get a more basic video.. which would still be more than enough for playback.. which is 1/2 height. Even in a full size case, one of these cards might be more preferable.. as they do not take up the same height as a full size card.
