Two features I like on this case are the ports for water cooling and the external audio, eSATA, and USB ports. There aren’t very many mid-tower cases out there like the NZXT Guardian 921; the ability to water cool without case modding is a great option.

Included with all of the standard cables for hooking up the front panel and the motherboard, is 3 temperature sensors you can place in your HDD slot, your CPU heat sink and for me the system sensor goes on the top of the case for ambient case temps.

There is a plethora of potential potent air pushing power. There is some alliteration for you. With the addition of a total of 3 120mm fans stock with this case you get all of the cooling you would want in a mid-tower case. There is one for your CPU, one for the exhaust, and one for your HDD’s.

If you are a fan of tool-less like me you will love this case. There are thumbscrews, HDD and ODD tool-less by rail or built in tool-less, and you get expansion slot tool-less. I do not trust the expansion slot tool less my self this style seems a little cheap so I end up using screws because I am a bit paranoid.
