Well, I took the plunge and ordered a Dtek unpainted heatercore + shroud kit today.
Either way I should be very happy with the increased performace of my cooling system.
Unfortunatly, I dont have time or even a workbench to make my own modifications anymore.......

So pre-modded is good.

I must say that looks like a mightly nice setup you got there. Too bad I dont have enough room in my own case for one
