This is a decent case and for a budget builder it is something that looks nice (not tacky), has decent features, and can support optical drives. I think 3 drives bays are a good idea because other things can go in there besides the obvious optical drives, fan controllers, reservoirs, hotswap bays, other accessories (the NZXT Hue is a great example). They really need to work on the editing though, there were a few typos and some parts with ambiguous wording.
Spec series is useless because you can't fit a decent Air cooler in them.
This case you can fit a decent sized AIR cooler in.
i have the spec 01 and dont find it useless, and it was cheap. I knew i couldnt fit an oversized air cooler in it so i put in a water cooler that was only a few more $$ than the hyper 212. I'm not a big fan of big air coolers, look unsightly and makes everything too cluttered imo.
