[Guide] NAS Killer 4.0 - fast, quiet, power efficient, and flexible - starting at $125


CPU Coolers


You probably won’t need one of these if you’re going for a prebuilt system, but you definitely will need one of these if you’re building it yourself.

The Thermaltake Gravity i2 will probably be the go-to recommendation considering it can adequately cool most 1155 processors (and it’s really cheap).

If you decide to go for another option, make sure it’ll fit (height). Otherwise you’re going to be really sad.

Other Parts to Consider


For the internal SAS HBAs and Warp Drive / Flash Accelerator cards, you may need a full height bracket. Good thing is that they are really cheap ($1), bad thing is that they may take a week or two to arrive.
