I think the newer Bitfenix series will have 2x USB 3.0 front headers: Merc and/or shinobi. I need to confirm that.
3. it doesn't have rubber pads for PSU to just lower the vibration... So dont get surprised if your table starts shaking when your computer would be on...
Overexaggeration. Besides, if you think about it if a table shakes just because a system vibration, that means the feet of the table doesn't have proper contact with the floor
TBH front dust panel blocks a part of dust being accumulated in the air but that's about it. Especially if you're living in a city, eventually dust is accumulated within the system. The only convinience of dust filters is that the pain of removing front panel fans to clean them is reduced by a lot.
One can't really expect a lot from 2-3k case. Having a solid construction with decent space and proper brass standoffs, screws are more important. People don't realize but some of the cheaper case don't even have proper threaded brass standoffs and screws. Some of these cases have front panel that rusts within 6 months, especially the USB ports. Before dissing such cases, you need to know how cases are made and how much it can cost.
Keeping all that in mind, cases like NZXT source 210 isnt bad either. But eventually such cases will come with 2x USB 3.0- because it just doesn't make sense to have a header which routes to 2x USB 3.0 ports but keep only one.
