I use this case

Independent laboratory testing proves that Sonata is three times quieter than a comparable high-performance mid-tower case. How quiet? Just 20.4 dBA. Which means Sonata is literally quieter than a whisper
and it looks nice too, with piano black polished paint
it costs around 100 euro's
