NZXT makes good cases, and has "crossed my path" as I searched for my own options. But I settled on the HAF midtower over the last year-and-a-half.
It depends on your priorities. My priorities were driven by cooling with minimum noise. I wanted a pressurized case with "high air flow." The HAF choice was based on these priorities along with my experience doing case-mods on old '90s-era ATX full-towers, and the HAFs eliminate for me a lot of "modding."
Often, side-panel fans affixed to the removable side-panel can generate vibration (and noise), but the 200+mm fans of the HAF cases are "low-noise" to begin with. In my case (pun), I block off the top-side fan vent with black foam art-board, and relocate the 200mm fan to the side-panel. You can dampen the vibration by using rubber-grommets on the fan mounts, or inserting a gasket cut from foam art-board.
But like I said -- your preferences, your priorities -- not necessarily mine . . .
We aren't too far off, I think we weigh factors in a similar fashion. I'm spending a lot of time reading reviews, impressions and user experiences but I have yet to find a case that intrigues me as much as HAF series.
Multi directional GPU cooling did wonders for me, even in the cramped case I have now.
The volume of a full tower case, combined with bottom, front, top and side panel mounted large & high quality fans have me salivating already. Water-cooling still hasn't regained my trust but the next best thing is air cooling with aftermarket parts.
Part of the reason I'm trying to save on one is that I plan to buy all Noctua fans for it. I already figured out how to make a blue print for custom dust covers. Again, kinda stuck on the HAF, trying to figure out of I could/should elevate the case to mount additional fans at the case bottom (externally)
Another (likely foolish idea) was spawned during this case hunt: I have 2 sets of short "tubes", ~145mm in diameter, about 6" long. One pair is copper, the other is thinner and plastic but it'ss sturdy, both should be able to carry the weight of at least ~60 lbs, I don't expected a fully loaded HAF932 to weigh more than 45lbs. If I mount the power supply at the top, I could use the tubes (especially the copper ones) to feed air into the bottom of the case by "dipping" the tubes into the top one of those mini coolers, so the case would stand on top of the mini cooler.
In theory, mounting the fans inside the tubes would draw the air from the mini cooler into the case via bottom vents. Because of a top mounted supply, the large top fan would have to go but one smaller fan should still fit at the top to expel hot air. If I do go this route, it will likely get ugly but I haven't used physical media in a long time and the best spot for the case is out of sight anyway.
