Nice setup. I recently built a micro ATX with a Z75 and a low profile AMD 7670, which has the exact same specs as the 6670, AMD just renamed it to match the rest of their 7000 series. The Core i5 and the Core i7 both make a lot of heat when under load. This is the first time I've gone with liquid cooling. I chose the cooling carefully as I've seen a lot of leaky systems. I'm running Debian Linux, which also influenced my hardware choices for compatibility.
Despite some media reports, there were no AK-47s involved in the incident
