I've long liked the Sonatas as quiet enclosures with high build quality per dollar for not-too-extreme systems—particularly the Sonata III 500 with its included 500w Earthwatts PSU. They simply feel and are solid and well-built, which customers appreciate, so I've used them for scores of rigs—just ones that didn't require insane cooling. This new one looks good, nothing revolutionary. If it were available bundled with the 500w (or better) Earthwatts for $80-$85 shipped, I'd buy a dozen and start building, maybe keep a few on hand for future builds. That bundle would sell fine at the $110-$120 price point too and I'd consider it to be well worth it, but given the deals I've gotten on the Sonata III 500 in the past, I think a lower price is possible and would make it popular, to put it lightly.
Only thing I would prefer is a bottom-mounted PSU.
This is the kind of case I like to see: well built, simple, reasonably quite, and at a good price. No fancy grills, flashy crap, etc.
