Have a look at SFFtime N-ATX V2
Very nice!
Too bad it won't have a chance of fitting my CPU cooler. It's limited to coolers of just 59 mm, whereas my Noctua NH-C14S is 115 mm, even if you mount the fan underneath the fins.

I'll have to consider other CPU cooling options, but I might need to pass this one by. Too bad it can't even fit the 66 mm NH-L12:
The other thing I'd point out is that my current case is positive-pressure with dust filters on the intake fans. This case is super-open, and would definitely want some periodic dust removal. My old PC had a heatsink that would clog up and required maintenance about every 6 months and that's an experience I'd rather not repeat (not that most heatsinks clog any more, but I definitely dislike "dust-trap" cases).

Plus, it has 5.25" bays. I forgot to mention that. It's basically the only case I could find that met all my requirements, at any price. 5.25" bays are getting rare, especially in smaller cases. However, if a case had everything else I wanted, I'd be willing to cope with an external optical drive.
