Remember what I said about noise levels in silent cases? This is what happens. The Ghost is able to do the best job of keeping our overclocked testbed quiet, but again the DS1 is able to handle the increased thermal load more gracefully.We have to keep in mind that the Silentium simply isn't designed for this usage scenario, and that's fine. But in the process, cases like the Ghost and R4 start to look like better deals. The R4 is more expensive, but the Ghost isn't.
