"overall we like the Core G3 as it's exactly what case manufacturers should be doing now that SFX PSUs are readily available. Thankfully, while it's blazing a trail, it's also a good case in its own right."



"Thermaltake Core G3 is a small case that manages to pack in an ATX motherboard yet it can easily hide under your TV. If you instead choose to stand the Core G3 on your desk as a tiny tower case and take a long, close look you will see the components inside the large windowed panel are inverted."
