The side panels of the case have handles and are fastened with spring-loaded thumbscrews. You don’t need a screwdriver to take the side panels off and you won’t lose the screws.
The GS1000 comes with two plastic stands.
Of course, you can do without the stands, but they make the case steadier and facilitate the intake of air through the vent holes that populate most of the bottom panel.
It is not easy to attach the stands irrespective of whether the case is upright or lies on its side. You have to lift it up with one hand and attach the stands with the other hand. The good news is that the stands have grooves for lifting the GS1000 up afterwards. We’d recommend you to place the case upright for assembly or put the stands on after you’ve assembled your computer system because the GS1000 will not lie comfortably on its side with the stands attached.
Inside, the chassis is robust. It is made from rather thick steel and every sharp edge is neatly rolled in. You can note that 5-inch devices are fastened with spring-loaded thumbscrews – you won’t need a screwdriver here, either. The mainboard is installed in the old way – on hex cap poles – and fastened with screws. By the way, take note how much space it is allotted. The GS1000 is meant for not only ATX but also for longer E-ATX mainboards. The latter variety is often installed in server platforms. Thus, the Zalman GS1000 can easily accommodate a top-performance workstation with two CPUs.
At the bottom of the mainboard’s mounting plate there are holes to lay the cables neatly behind the mainboard. The edges of the holes are covered with plastic so that they did not cut the cables. There is quite enough of space for the cables in there, which is much handier than making bunches of cables within the main interior of the system case.
But let’s get back to the interior. There are indeed two seats for 120mm fans at the top of the case, below the top covering, but only one fan is installed by default.
Both fans have 3-pin power connectors for the mainboard. This is not expedient because there is usually only one such connector at the top of the mainboard, so you will have to stretch the second fan’s cable through the entire case. And this cable is not long enough to be hidden behind the mainboard’s mounting plate.
The bottom part of the case (with the PSU compartment) is separated from the top part with a small partition. There is no such partitioning of the case into two separate compartments as we have seen in Antec’s products.
The vent holes in the bottom of the case are meant for 120mm fans as is indicated by the characteristic bulges with threading in the appropriate locations. While the central fan would be helpful because it will cool the graphics card, installing a fan under the PSU is hardly reasonable. It just won’t have enough of free space to create a strong airflow.
Thumbscrews seem to be the characteristic feature of the GS1000. You will find them even on the expansion-slot brackets. This is a handy solution but only for people with slim fingers. We were surprised to find the screws to be so tightly fastened that we had to undo them with a screwdriver. This had been done to prevent the screws from unfastening during transportation.
To install a power supply, you need to attach a special frame to it. This frame allows to place the PSU upside down, which is good for models with 120mm or 140mm cooling fans.
Then you can simply roll the PSU into the case along the rails with plastic wheels. The PSU is fixed in place by fastening the frame to the chassis – with thumbscrews again.
