Would like to share some minor update on my HAF 912. Bought some Xiggy 12cm fans and fan filters. Not really satisfied with the casing original dust filters.
Here are some pics:
Here are the dust filters. One 14cm and three 12cm. Got dis filters from niclasteoh frm garage sales.

Install a 12cm fan at the side panel as well as dust filters.

Not satified wit 1 filter , i added another 14cm filter outside of the side panel.

Took out the preinstall 20cm fan at the front, and installed two 12cm fans wit filters.

Heres how it looks wit the plastic front panel install back on.

Installed two 12cm fans at the top as well. Took out the 20cm fans.

Here are the overall look.

Night mode:

I really luv those dust filters. It does the job really well. After only 1 week installed, i can see all the dust trap nicely at the filters.
As for the airflow, i dont really think it affects much coz my internals are still in good temps.
BUT if u guys really need to know the effects of the airflow after installing these filters, here is a detail test results:

The actual article on this test is from here:
