The ALM Busy Circuits 52HP 9U Powered Eurorack Case balances space-saving geometry with an impressive power profile. It provides a clean, vertical canvas for focused multi-row performance layouts or hybrid setups alongside desktop studio gear.

The case is constructed from lightweight, durable anodized aluminum. Its distinct vertical "portrait" proportions distribute 156HP of total modular real estate across three discrete 3U rows. This compact footprint makes it highly portable and exceptionally easy to fit onto crowded desks, next to DJ setups, or inside travel bags.

At the heart of the system is an integrated, high-quality switched powered busboard. It provides up to 2A of current on both the +12V and -12V rails per row, keeping power-hungry digital modules perfectly stable. Power cleanliness is guaranteed by an ultra-low 100mV ripple noise specification at max load, combined with built-in protection against overloads and short circuits. The internal busboard provides 18 keyed headers to securely hook up your modules (please note: there is no native 5V rail line). For physical installation, the case replaces loose sliding nuts with fixed M3 threaded rails, offering up to 42mm of depth clearance to accommodate thick, multi-PCB module designs. The entire package comes complete with an external 5A power brick.
