A first Eurorack case should be at least 3U x 84 HP, and 6U x 84-104 HP gives room to grow without outgrowing quickly

Noise Engineering’s practical recommendation for a first system is to get a case slightly larger than you currently think you need, since you always discover more modules you want. The minimum viable case is 3U x 84 HP. A compact performance-focused option is the 62 HP Intellijel Palette. The recommended range for a well-equipped system with growth potential is 6U x 84 HP or 6U x 104 HP. The key insight is that case costs rise less steeply than the cost of replacing an undersized case — undersizing forces you to sell and rebuy, which is expensive. Buy bigger than your current patch plan suggests.

Examples

At 3U x 84 HP, you have one row for 8-15 modules. At 6U x 84 HP, you have two rows and can build a complete voice with utilities and sequencers.
