On Figure 10 you have an overall look from the interior of this case.  Even though you can remove the right side panel, the motherboard tray is permanently attached to the chassis.

This case comes with thumbscrews for fastening daughter boards to the case. We think the use of this kind of screw is perfect, since several screwless mechanisms use cheap plastic parts that break while you are building your PC. On Figure 11 you can see the rear 120-mm fan and the thumbscrews. The fans that come with the case use a three-pin connector, allowing you to connect them to your motherboard and thus monitor their speed.

Zalman GS1000 has also space for the installation of two 120-mm fans at the bottom of the case, as shown on Figure 13. If you install fans here you should also install the feet that come with the case.
