## Overview
The Phanteks Enthoo Primo PH-ES813P_BL is a full-tower PC case purpose-built for advanced water-cooling builds. Its construction combines an aluminum frame with an acrylic side window, offering both rigidity and a clear view of your custom loop or component layout. Out of the box, it includes five 140mm fans (two front LEDs, one top, one rear, one bottom), providing excellent default airflow. The case supports up to 16 fans total and allows radiator mounting at nearly every fan position except the HDD cage, giving extensive water-cooling flexibility. Motherboard compatibility spans SSI EEB, E-ATX, ATX, and MicroATX, accommodating everything from standard builds to server-grade boards.
This case supports SSI EEB, E-ATX, ATX, and MicroATX motherboards. The power supply mounts at the bottom and can fit up to two PSUs, ideal for dual-system or high-wattage configurations. Storage options are generous: five 5.25-inch external bays, six 3.5-inch shadow bays, and twelve 2.5-inch shadow bays. With eight expansion slots, even triple-slot graphics cards fit with room to spare. Note that the case's large footprint (approx. 22.7 kg) requires ample desk or floor space; measure your installation area before purchase.
The Enthoo Primo was released in 2013, yet its water-cooling-centric design remains relevant among enthusiasts. The aluminum construction and spacious interior (width sufficient for wide radiators) cater to custom-loop builders. While it lacks modern conveniences like USB-C front ports or ARGB control, its radiator capacity and drive flexibility are still competitive.
Custom water-cooling enthusiasts: The abundance of radiator mounting points (every fan position except the HDD cage) makes multi-loop layouts straightforward. The stock fan complement provides solid baseline cooling. High-storage users: With six 3.5-inch and twelve 2.5-inch drive bays, this case suits NAS replacements or video-editing workstations that need many drives. * Dual-system or workstation builders: Support for SSI EEB/E-ATX boards and dual PSUs permits powerful multi-GPU or server-like configurations.

## Things to Consider
The Enthoo Primo is heavy (~22.7 kg) and large, so it's not suited for frequent moves or desktop placement. It lacks modern front-panel USB-C and ARGB headers, which may require adapters or hub add-ons. Check the retailer's page for the latest price. Consider whether you truly need the Primo's extreme drive capacity and dual-PSU capability before committing.
