If you’re building a powerful desktop PC but limited on space—or you just prefer a cleaner, more minimalist setup with a smaller footprint—then a compact ATX case is your best bet. These cases manage to house full-sized ATX motherboards while saving desk or floor space, all without sacrificing airflow, aesthetics, or modern features. The trick is finding those few well-designed models that really balance form and function. In this guide, we’ll explore some of the best compact ATX PC cases available today and explain why they’re worth considering for your next build.
Why Choose a Compact ATX Case?
Let’s face it: standard mid-towers and full towers can eat up serious space. Compact ATX cases aim to shave off just enough bulk while still supporting full-sized components like GPUs, CPUs with chunky coolers, and even custom water cooling setups. Here are some key reasons why people opt for these cases:
- Space efficiency – Workstations or gaming rigs can easily fit into smaller home setups.
- Portability – Smaller cases are often lighter and easier to transport for LAN parties or moves.
- Aesthetic appeal – Clean, minimal builds look more refined in compact cases.
- No compromise on compatibility – Most compact ATX cases still support modern GPUs, full-sized power supplies, and multiple storage drives.

Buying Considerations
When shopping for a compact ATX case, it’s important to keep a few things in mind:
- GPU Clearance: Some extremely compact cases may not support ultra-long graphics cards. Always check max supported length.
- Cooling: Look at how many fans are included, and what’s the max number supported. Also factor in radiator mounting options if you’re using a liquid cooler.
- Cable management: Tight interiors mean cable management is more critical than ever. Look for cases with Velcro loops, routing channels, and clearance behind the motherboard tray.
- Expansion: How many SSDs/HDDs can you mount? Do you need an optical drive bay or front panel USB-C?
