The top panel features a 140 mm fan with a switch available on the rear panel to select between high and low speeds. At low speed it rotates at 800 rpm, producing an airflow of 33.6 cfm and a noise level of 21.8 dBA; at high speed it rotates at 1,200 rpm, producing an airflow of 58.9 cfm and a noise level of 26 dBA. This fan must be connected directly to the power supply, so you can’t monitor its speed through your motherboard.
In Figure 6, you can see the rear panel from Two Hundred. As you can see, the rear panel isn’t painted. The power supply is installed on the bottom of the case, a feature that is usually only available on more expensive cases. There is a 120 mm fan on the rear panel also with a switch for you to select between two speeds. At low speed it rotates at 900 rpm, producing an airflow of 30.1 cfm and a noise level of 16.9 dBA; at high speed it rotates at 1,500 rpm, producing an airflow of 51.2 cfm and a noise level of 27.9 dBA.
This case has two holes for you to pass hoses from water cooling devices, but these holes must be broken to be used: no rubber protection is available. Also the slot covers used are from that type that needs to be broken, usually found on low-end cases.
The right panel features a tab for installing a padlock or a warranty seal, if you want to restrict people from opening the case.
Now let’s take a look inside Two Hundred from Antec.
