The top radiator mount you have is quite nice, and the easiest to set up. When i saw your second radiator though, i thought this: What are you gonna do when you take the sidedoor off? This would be very hard to mount and connect with hoses without taking the side panel off. You could use quick connections
Another tip: You can mount your radiator on the bottom part, where there is made out holes for a fan (or a radiator). You can just cut a bit out of your harddrive cage, and install that sucka. Hope this helped!
