Manufacturer Contact Info

The Phanteks Enthoo Pro 2 Server Edition is a full-tower workstation and server case for builders who need SSI-EEB motherboard support, 11 expansion slots, and extensive cooling capacity. It supports up to 15 fan positions and large radiators, making it suited to high-performance systems where interior space and airflow flexibility matter.

Recommended For

Workstation and small-business server builders who need SSI-EEB/server-grade motherboard support and room to combine server and consumer hardware in one tower.
Builders assembling systems with multiple PCIe cards or GPUs who want 11 expansion slots and a side bracket for directing additional airflow at the CPU and GPU area.
Home-lab and storage-system builders who want a full tower for several hard drives, server components, and future expansion; the case supports up to 10 3.5-inch drives, though only four HDD brackets are included.
Enthusiasts planning a large custom liquid-cooling or high-heat workstation build who need flexible radiator placement and are prepared to choose and install their own fans.

Real-World Use Scenarios

When building an AI or compute workstation with several GPUs, the case provides room for a dense card layout and a bracket for directing airflow toward the CPU and GPUs; plan on adding fans and checking temperatures under sustained load.
For a dual-socket server or workstation using an SSI-EEB board, multiple PCIe cards, and fast storage, the spacious layout accommodates server-grade components without limiting the build to consumer-sized boards.
When assembling a home lab for file storage, media services, or virtual machines, the drive mounting options leave room to build out storage alongside the system hardware; check your planned drive and cooling layout before buying, since installed cages use interior space.
For a workstation or server with high CPU heat output, builders can use large radiators and multiple fan locations to shape a liquid-cooling setup; the case ships without fans, so cooling performance depends on the components and fan configuration selected.
