Who needs an optical disc drive anyway?
"It's a fascinating concept and one that's only been attempted by only a handful of case manufacturers. There are some fairly obvious limitations, though, such as a 65W recommended TDP (95W max) for the ST-FC5S EVO WS that we're looking at. So if you're looking for a cool way to cool your overclocked Core i5-3570K this won't be it, but for your average LGA1155 Pentium or Core i3 it should be ample."
