I will say one thing about this hs, it is highly recommended that you have a removable motherboard tray. If my awesome $31 case didn't have a removable mobo tray I think it would have been much more difficult. You would have to have someone hold it up for you. It weights about 2.2 pounds.
The thing moves a lot of air around right in the middle of your case. So like the description says it basically does also cool down ram, northbridge, vga, etc. My case works especially well because there is a fan on the side of the case pointed directly at the processor so it feeds air right into the zalman.
Installation was easy, took all of 3 minutes. All you have to do is twist a couple screws into a couple nipples.
