does your pc distract you when making tunes

[BloodStar]

I would go for the following

Zalman Flower CPU cooler

Silent Power supply (fanless ones are good)

Silent Max Hard Drive enclosures

Internal noise padding foam.

OR

Getting bigger fans and putting your machine into a home built case...

Yes, but be careful with the Hard Drive enclosures. - they can raise HDD temperature. Same with noise padding - it can raise the temperature inside the case.

Also when buying CPU cooler you should know what is the airflow inside the case. because you can buy nice CPU cooler but it can stop the airflow and then you will have higher temperatures than before.
