InWin RS104-02S-S300: a 1U server case for home labs
A homelab enthusiast shared the InWin RS104-02S-S300, a compact 1U server case with a built-in 300W power supply. It's aimed at people who want to build their own small server that fits in a standard server rack.
The InWin RS104-02S-S300 is a 1U server case, meaning it fits into a standard server rack slot that is about 1.75 inches (4.4 cm) tall. This makes it much more compact than a typical desktop tower, which is useful if you want to stack multiple servers neatly in a rack at home.
The case comes with a 300W PSU already included, so you don't need to buy a separate power supply. For Mac mini server users curious about alternative hardware options, this represents a traditional rack-mount path — useful context when comparing form factors for a home server setup.
Key points
