Summary: Generally, cases with a power supply are intended for the budget market. I believe Antec had this in mind with the Antec Sonata III Case. This product is mostly steel with a stylish plastic front bezel. There are 3x5.25", 2x3.5" (ext), and 4x3.5" (int) drive bays. Conveniently located at the front are 2 USB2 ports, eSATA port, a microphone jack and headphone jack.
Conclusion: With a price-tag in the region of £79, the Antec Sonata III 500 isn’t ultra cheap. However, that sum also buys you a fairly high-spec'd power supply that's currently priced at £52.88 from YOYOtech and doesn't seem to be selling for significantly less anywhere else. Although it's perhaps not appropriate to simply subtract the retail cost of the PSU from the price of the case, if you did so, it would make the cost of the case itself falls to only a little over £26.
Excerpt: During the last couple of years quiet computing has really made its big entrance. Markets are filled with numerous products from rubber grommets to silent fans, but still the case remains the single most important component when trying to build as silent setup as possible. Antec Sonata-series cases have been popular amongst the enthusiast for years already and now the series has reached its third version.
Conclusion: The Antec Sonata III is a worthy successor to the Sonata brand name. It is a beautiful case, which is well designed. Having an eSATA connector on the front is a welcome addition. The addition of the energy efficient EarthWatts PSU, makes this case a better package than the older Sonatas. I have very few complaints about the Sonata III and feel it would make a great case for either a HTPC setup or as a regular desk workstation.
Summary: The Antec Sonata III is a great combination of a high efficiency brand name power supply with ample power under the hood to supply a fairly high end system with SLI/Crossfire and quad core inside a very solid case. It is hard to find such a combination these days, especially at this price point. The internal case layout is simple but works quite well.
Pros: Great price for a solid PSU & case combination, High efficiency 500W SLI/Crossfire capable PSU included, Case construction is very solid, Perfect glossy paint job, Interior layout simple but effective, HDD mounts on rubber spacers, Solid front and high quality plastic, Removable dust filter in front, 12 cm Tricool fan with controller included, Front I/O with eSATA
Cons: Installation of external 3.5 inch and 5.25 inch drives easier but still complicated, No active cooling for hard drives, Power & Reset button are covered by door, LED are both blue - what is what?, No Firewire connectivity up front, Door looks good on outside, not so good on the inside, Door is held shut by a plastic clip - magnets would have been better, Paint job is a fingerprint magnet
Conclusion: The Sonata III is Antec's best "Quiet Computing" case yet. The case has great looks and exceptional quality. Even though the case is fairly simple, it still has some excellent features that work extremely well. The case is well vented, but nearly silent with the variable speed cooling fan and Earthwatts PSU. Speaking of PSU, Antec has spared no expense by going with the Earthwatts series.
Conclusion: I was surprised at how quiet this case really is. However, there are even more things that Antec could have done to make this even better. Foam covered side panels would absorb noise and rubber grommet’s on the 5.25” bays would stop annoying optical drive vibration. Overall, for the small asking price of £70, you are going to get an energy efficient power supply capable of powering most PC’s this case will house, and a quiet case with some nice tool-less design.
Pros: Very quiet, Reasonable cooling, Included 80+ PSU
Cons: Could have more noise prevention, Little small
