Thank you, your rig there is pretty sweet too, I love the watercooling on wheels idea
And the sound card is an Asus Xonar DS (the original PCI version). I got into some music production around the time I bought it last year, so I wanted something to fill in that missing sound gap until I can upgrade to a proper M-Audio card or some sort of audiophile card such as an HT Omega. But anyways, for me the difference in sound is noticeable. A lot richer and it can drive my headphones (Shure SRH440) better than the onboard on my older Gigabyte GA-970A board. It does come with a low profile bracket too.
