Yes you'll have to uninstall the motherboard for the back plate. Not that it matters much, it's a pain either way. Everyone likes the Cooler Master 212 EVO, it's as good as it gets for under $50 (it's about $25). If you don't feel up to messing with backplates, the TX3 is the smaller version, and it uses the normal retainer, or whatever you want to call it. I run the TX3, my CPU's much less powerful than yours but mines more than enough for me for what that's worth.
