depends where you buy its but i can buy it for 150 euro if i look in the best webshop here in The Netherlands, so its not 150 for you. :s
but you can also buy a case from around 100 euro and buy very silent fans like be quiet! Silent Wings those are pretty quiet or Scythe Slip Stream.
like 2 fans so thats around 20-30 euro and depends on howmuch fans you cna place there so and your case will be silence.
PS:i have the Silent Wings in the Antec 1200 and i like it.
Some more example cases:
don't know if this one is good; NZXT Phantom Black but its looks badass :p
Antec 1200 or Coolermaster 932. depends on the prices u got there :)
