PCMag.com's article on Making a Quiet Case Quieter features the Antec Sonata II with the AcoustiPack pre-cut kit.

"...it's an attractive case and has room for expansion. This case also has a sturdy but relatively accessible interior, so it's fairly easy to work on. (A large cooling duct that vents air from the CPU cooler out of the case gets in the way, but that part is easy to remove.) Those are not the only reasons for choosing the Sonata II, however: the AcoustiPack precut noise reduction kit really won us over. You can buy noise reduction plastic or foam materials, of course, and you can cut them yourself for any PC case. But anyone who's tried to cut a straight line through a piece of foam with a craft knife or Dremel will understand the appeal of a precut kit.

The Italian website pcimprover.it installed their Antec Sonata II PC case with a GlobalWin SAK 38 heat sink. They then took sound measurements both with and without the AcoustiPack™ Pre-Cut Soundproofing Kit installed.

Their tests showed that with the AcoustiPack™ soundproofing kit the noise emissions were reduced from 45dB(A) to 36dB(A) which is approximately 3 times lower noise output! It also showed that the frequency of sound was also lower.

They would recommend AcoustiPack™ to anyone wanting to significantly reduce the noise of their PC without sacrificing performance. [full Italian review]

ExtremeTech.com built a modded Antec Sonata II with an Athlon 64 FX-57, Seasonic S12 600 PSU, Zalman CNPS 7700 and eVGA GeForce 7900 GTX. The resulting SPL (A-weighted) was an extremely quiet 29dB(A)!

"...we didn't expect the Sonata by itself to be quiet enough, but then we discovered the AcoustiPack™ pre-cut noise reduction kit for the Antec Sonata II. It's certainly true that you can buy noise reduction plastic or foam materials, cut them yourself, and use them with any PC case. Anyone who has ever watched in horror as someone tried to cut a straight line with a craft knife or Dremel will instantly understand the appeal of a pre-cut kit...

"...the system was eerily quiet overall, in a quiet office with nothing else running. At one meter from the front, you had to strain to hear the system run, even at full bore...

"Pros: Easy to apply; relatively low cost; works well
Cons: Need to take care in applying the material; this kit is only for the Sonata or Sonata II
Summary: If you want to build a quiet PC, then this kit can give you a big head start, with no need to measure and cut. And it's fairly inexpensive." Rating: 9/10 [full review]

"Nice one. I used it and I am pleased." Georgi, Bulgaria.

"Simply incredible. I saw this kit in a friend's computer and was astonished by the quality and quietness of his computer." John, USA

"Makes the silent chassis even more silent... Thought it was impossible, but no..." Sonny, Sweden
