Is there any difference in temp between the bottom group and above one? (I know those additional fans will help to push hot air) I don't recognize, what cards is it? One more thing, is that unpowered risers?

I think that setup will work great on reference cards (AMD) related to the air-flow that will push hot air to one side. Good setup, I like this.



So, you are using two PSU (server and consumer PSU). But my question is, is there any magic trick related to the glass above the PSU?  . Good work!
