With the SG03 internal design being original, we had expected the installation to take a bit longer than normal for a micro ATX case but there were a few minor snags along the way. We had begun by installing the optical drive, which was a SATA-based ASUS DVD-RW drive followed by the Tyan Toledo i965R (S5180) motherboard. This was the same hardware we had used in our recent SilverStone SG01W review and of which everything had installed smoothly. Both the optical drive and motherboard installation had gone well, but when it came to the power supply we had hit a few snags. The power supply being used was the SilverStone Element ST50EF-Plus Short Cable. Before mounting the 500W power supply we first connected the 24-pin and 8-pin motherboard power connections seeing as the power supply mount is above the motherboard's CPU socket area. However, with the minimal room above the micro ATX motherboard area and the SilverStone Nitrogon NT06 taking up most of that space it was rather difficult to install the 8-pin cable. Due to the short cables, it was not possible to connect the power leads to the motherboard prior to installing it in the SG03 However, the SG03 solely isn't as fault but equally the Tyan Toledo i965R and the Nitrogon NT06 can be blamed. We had worked out this minor problem after a few minutes of bending and rerouting the cable. A majority of users that pick up this case will likely not run into this issue.
The other minor issue we had with the power supply installation was the limited room between the power supply and the top of the case with the 5.25" optical drive bay being in between. The SATA power cable for the ASUS drive was rather difficult to install with large hands, but after some maneuvering it was properly fitted. Like we had done when installing the ST50EF-Plus SC and Nitrogon NT06 in the Sugo SG01, the 120mm fan on the power supply was positioned to draw air from the Nitrogon heatsink thus eliminating the need for a dedicated fan on the CPU cooler. With the PSU installation complete, we had no problems with the rest of the build when it came to the ATI Radeon X1800XL graphics card and the Seagate SATA 2.0 hard drive.
