Look inside & Cooling

Antec’s entry level case has some high quality finish, we found no sharp edges when working with this enclosure; opening the Three Hundred can be done with tools thanks to the included thumb screws:



Inside the case you’ll find an installation manual and two bags of screws to get your hardware installed.



The layout at the inside is quite simple yet practical, the 3.5”/5.25” bays fill the whole front area of the case. You can see the wires of the top 140mm fan dangles downwards.



A close-up of the fan power connectors (4-pin) and speed control switches, default set to L, a medium and High setting are available too.



Removing the front panel gives access to the three 5.25” bays, as well as the optional case fans, 2x120mm can be mounted here.



A picture of the right of the case reveals room behind the 3.5” bays to hide you cables, there are also cable zip-ties to help you with this. The metal front cover which can hold a 120mm fan can be easily removed with the included thumb screws.



With the front panel removed you can remove the dust filter to clean it out:




The bay covers can be easily removed without tools and replaced when needed.



Installation

There are no fancy features for mounting the HDDs or CD/DVDrom, the PCI slot covers are also held in place by regular screws; cost cutting had to be done somewhere. For the HDDs Antec included a bag of thumb screws, so installing them is quite easy;
