Suprised no one said what the plastic dohicky was for it is for sticking to things and running wire ties throught for cable management.
Yup, someone from a different forum (where I posted this too) said it is called a ziptie mount. I just needed the term and it can be googled easily. I just don't know the exact name of these things .. Now I guess I know how it works. lol
I have another problem, since these ziptie mounts are sooo cool .. my case only came with ONE! I have to find a place to buy these stuff!
Thanks for your reply. The only problem is my F_panel audio cables has a rubber coat already (made by Coolermaster) ... Can I just use this in F_panel USB OR the power/reset/speaker/etc cables that are scattered?
EDIT: F_panel USB also has a rubber coat with it already
