Glad to know that you had the same questions that i had, between 540 and X9. Saying that you know the X9 I do have some questions. I do know that you can move the window panle to the vented side,, but is it possible to put the window panel on the top of the case? I want a windowed top so you can see the water cooling on the mob.(I do understand that the top is a excalint place to put a couple of 480 rads and will be losing that.) and i know that the case is large can you post a pic of where you placed, or even your set up right now?
