Frequently Asked Questions

Common questions about CostaBox builds.

What is Costa OS?
Costa OS is a custom Arch Linux distribution built for people who use AI daily. It ships with Ollama pre-configured (Vulkan backend), voice control via Whisper, agent navigation that lets Claude Code interact with any application, and a Hyprland tiling compositor. It includes development tools (VS Code, Docker, pyenv, nvm), gaming support (Steam, Lutris, Proton), and local model routing between different LLM sizes.
Can I play games on CostaBox?
Yes. Both builds include modern GPUs (RTX 3060 12GB or RX 9060 XT 16GB) with full Vulkan support. Steam, Lutris, and Heroic Launcher work out of the box. Proton and DXVK handle Windows game compatibility. Costa OS runs Hyprland, a modern Wayland compositor with smooth performance for both gaming and productivity.
What LLM models can I run on CostaBox?
The CostaBox (CO-12, RTX 3060) has 12GB VRAM and comfortably runs 7B-9B parameter models at full speed. The CostaBox Pro (CO-16, RX 9060 XT) has 16GB VRAM and handles models up to 14B parameters comfortably, with 24B-27B possible at reduced quantization. Both include Ollama pre-installed with one-command model downloads.
Can I install Windows instead of Costa OS?
Yes. During configuration you can choose Costa OS (default, free), Windows 11 Pro, or no OS (bare hardware). All hardware is standard and works with any operating system. The Windows option includes a licensed copy pre-installed.
How is CostaBox different from building my own PC?
CostaBox is assembled, burn-in tested, and warrantied with Costa OS pre-configured. You skip 10-20 hours of parts research, compatibility checking, assembly, driver troubleshooting, and Linux configuration. Ollama, GPU drivers, and the development environment work immediately on first boot. The hardware carries a 1-year warranty on all components.
Does CostaBox come with a monitor, keyboard, or mouse?
No. CostaBox ships as the tower unit only. Any USB keyboard, USB mouse, and HDMI or DisplayPort monitor will work. The RTX 3060 build has HDMI and DisplayPort outputs; the RX 9060 XT build has HDMI and DisplayPort outputs. Both support multi-monitor setups.
