Summary: The Zalman GS1000 Case is available in two color options and is made from aluminum, steel and plastic. The side panels are aluminum, inside is steel, but the remaining outside is plastic. At the front there are four 5.25" drive bays but two have a 5.25" to 3.5" drive bay adapters. Something unique to this case is the SATA Hot Swap HDD Cage system for the bottom three HDDs. The SATA data & SATA power connectors are inside the case.
Excerpt: At first glance, Zalman’s GS1000 chassis looks like it’s a going to be a tool-free computer builder’s dream. And in many ways, it is. Zalman peacocks the hot-swap bays for your hard drives by placing them right on the front of the case, eschewing the more traditional combination of side-facing drives with a front-facing cooling fan. And many of the case’s screws are spring loaded.
Pros: Lots of internal room, lots of drive bay space in a hotswap design, parts kept in check and off the floor using spring-mounted screws.
Cons: Optical drive installation a formidable task, fan holes blocked by plastic grate, minimal front-panel connection options.
