GMC Bulldozer R-4
As with most enclosures, two thumbscrews hold the side panels in place, so removing these gives access to the internals. The case looks to be very small and compact. One would only wonder how this case would hold the magnitude of an ATX motherboard and power supply. Once you see that they eliminate the ODD to the external of the unit you gain the extra room on the inside. The HDD brackets to the side erase the drive bay cage that would take up most of the room.
A rear black 120mm fan is mounted; however there are two grills for 80mm fans so this fan can be removed and replaced by dual 80mm fans. A rear black 120mm fan is mounted; however there are two grills for 80mm fans so this fan can be removed and replaced by dual 80mm fans. There is another fan on the side panel – this time an 80mm one – that uses a Molex connector. One of the diodes also originates from here but can be placed anywhere in the case.
The whole front panel can be removed by simply applying a little force to pull it off. This reveals the fan which is again 80mm but this time it’s constructed of clear plastic and will give off a blue or red light from its LEDs once powered up. The LED fan at the front has a removable dust filter to stop any debris infiltrating the case. The fact that it is so easy to remove is great for cleaning purposes.
For the high-end users who want to use the extra fan, air holes are provided at the bottom and rear side. To remove the heat from CPU and high-end graphic card, R4 supports CAG (Chassis Air Guide) 1.1. There is enough space between the expansion slots and HD cage to accommodate a graphics card up to 10.5” long, so if you plan on trying to install a new Radeon 5870, for example, don’t bother since it just won’t fit. Chances are, however, if you can afford a new flagship monster graphics card then you’re probably looking for a full-tower case anyways.
