Depends what your into i guess. Me for example, im over the Antec900 look-a-likes, even that actual shape. Like i mean, in the beggining, it was all about some desktop box you can slap your monitor on, then it was the tower concept which came to an end about 15 years ago, but everyone still clings onto.
For my everyday use, i now use a HTPC chasis with my hardware in it, and im actually considering the Thermaltake Dh202. I have several towers and im bored of them. Ive painted them, hydrolics, pheumatics, gas, ln2, watercooled, custom aircooled, lapped, chopped and even dipped, so its time to move on for me.
Maybe this is a little too chunky for me, and im not happy with the positioning of the PSU, but im always open for new cases. I think before we go into the next era of cases, we will have to wait for the motherboard to be redesigned.
