The cutout for the cooler’s back-plate allows to take the cooler off without uninstalling the mainboard. You may not be able to do that if the CPU socket on your mainboard is located in a different place.
This system case offers two disk racks, each for three devices. They support hot plugging and can be accessed without opening the chassis.
Just open the doors and access your HDDs. By the way, Zalman offers the MS1000-HS1 system case which is exactly the same as the MS1000-HS2 but offers only one HDD rack.
It is easy to install HDDs into the rack. Take the guide out of the rack, put the HDD onto the guide, fix the HDD in the vibration-absorbing pads by moving two small levers, and insert it into the rack. The guides are made from rather flimsy plastic, but they are not supposed to work under heavy loads after all. The lack of rattle is the only thing expected from them.
The rack is cooled by a 92mm fan fastened at its back. There is a 3-pin power connector nearby, which is integrated into the rack’s common power supply system. Thus, the whole rack requires only one 4-pin connector from the PSU. There is also a small switch that lowers the speed of the fan. By default, the system case comes with only one fan (ZM9225ASH). You have to purchase a fan for the second rack separately.
Overall, the HDD racks are very good. The only thing we might wish is that the plastic guides were replaced with metallic ones.
5.25-inch devices are fastened by pressing and moving a small bar. It’s easy and simple but if you don’t like this system, you can secure your drives with screws as the necessary screw holes are all present.
The front-panel faceplates are fastened with screws to the holes in the drives rack. If you want to install an external 3.5-inch device, you should replace the default faceplate with the one that has a cutout and fasten the latter with screws, too.
The system case comes with two guides for installing 3.5-inch devices into the 5.25-inch bays. These guides are obviously designed for HDDs as is indicated by the vibration-absorbing pads.
There is a special adapter that allows installing two 2.5-inch HDDs into the guide. Zalman must be aware of the growing popularity of SSDs among computer enthusiasts.
It is quite easy to assemble a computer in this system case but laying out the cables is a problem. The hidden space is too narrow and we had to lay them carefully just to be able to close the side panel. Some of the cables with various connectors had to be routed back into the main interior volume. It would be much easier if the chassis were just 1 centimeter wider.
As for graphics cards, there is a generous 300 millimeters from the back panel to the fan on the HDD rack. And even if you’ve got a Radeon HD 5970, you will be able to install it into this system case by simply removing the HDD fan.
The space above the mainboard is larger than in the Cooler Master case, yet only slim radiators of liquid cooling systems will fit into it.
