HAVN HS 420 Base Edition White Case E-ATX

HAVN HS 420 Base Edition White is a middle tower white case with tempered glass, aimed at mid-range to high-end configurations, including more serious E-ATX builds. It supports ATX, Micro ATX, Mini ITX, and Extended ATX motherboards, so you have quite a bit of flexibility in choosing a platform. The internal space allows for graphics cards up to 480 mm and coolers up to 185 mm, which means that practically all massive GPUs and high-end air CPU coolers will fit comfortably. The package does not include fans, giving you the freedom to choose exactly the airflow configuration and brand of fans you prefer.

What you get

This chassis is clearly oriented towards airflow and expandability: you have positions for fans on the top, bottom, sides, and back, allowing you to build a strong front-to-back or bottom-to-top air tunnel depending on where the case will sit. Up to 3x 120 mm or 2x 140 mm fans on top, another up to 3x 120 mm or 1x 140 mm on the bottom, and side space for up to 3x 120 mm or 2x 140 mm give you plenty of options for combining intake and exhaust, so both a powerful CPU and a heating GPU can stay under control. With up to 4 x 3.5" and 8 x 2.5" slots, you can create a serious RAID array, ample space for games, or a workspace with many project files, without worrying about space. The I/O panel with USB 3.2 Gen 2 Type-C and two USB 3.2 Type A ports allows you to connect modern external drives, peripherals, and phones directly from the front, without rummaging around at the back. The separate power supply compartment supports PSUs up to 200 mm, which is sufficient for most serious power supplies for high-end configurations.

• Case form factor Middle Tower supporting ATX, Micro ATX, Mini ITX, and Extended ATX motherboards, so you can use both standard and wider E-ATX boards.
• Space for graphics cards up to 480 mm, allowing installation of long high-end GPUs without compromising front space.
• Support for CPU coolers up to 185 mm in height, suitable for massive air towers and more aggressive cooling solutions.
• Rich cooling options: on top 3x 120 mm or 2x 140 mm, on the bottom 3x 120 mm or 1x 140 mm, side 3x 120 mm or 2x 140 mm, and back 1x 120 mm, allowing flexible airflow configurations.
• 4 x 3.5" and 8 x 2.5" storage slots, suitable for systems with many games, project files, or local backups.
• Front I/O panel with 1 x USB 3.2 Gen 2 Type-C, 2 x USB 3.2 Type A, and HD Audio, providing quick access to high-speed external devices and headphones.
• Tempered glass side panels for a clean view of the components and RGB, without sacrificing strength compared to regular glass.
• Support for power supplies up to 200 mm in length and lack of built-in PSU, giving you the freedom to choose a quality power supply according to the needs of the system.

Who it is suitable for

This case is a good choice if you are planning a serious gaming or workstation build with a long graphics card, plenty of storage, and want flexible airflow with many fans. It is also suitable for people who care about a clean internal appearance and tempered glass, and are considering future upgrades to E-ATX platforms or more drives. If you are looking for something super compact or with included “out of the box” fans, this chassis is not the most logical choice.

The strongest aspect of HAVN HS 420 Base Edition White is the combination of serious internal volume, rich cooling options, and many drive slots, without locking you into a specific fan or power supply configuration.
