Havn cuts HS 420 size 19.4% and weight 29.5%, adds cooling and easier fan access

Havn just tried to solve the biggest complaint about its HS 420 case with a new version called the HS 360. At Computex 2026, the company says the HS 360 is 19.4% smaller and 29.5% lighter, while staying “very similar” to the HS 420.

The timing matters because custom PC builds have a pattern: people will tolerate a pain point during the build if the final machine looks great and runs cool. But with the HS 420, the pain was baked into the hardware itself. Havn’s pitch with the HS 360 is that it keeps the premium “easy to build into and looks great once the build's done” promise, while shrinking the case and shaving down the weight that makes everything harder before you even start.

So how do you shrink something without turning it into a compromise? Havn’s answer is design changes that target the physical constraints created by a smaller chassis. The case uses panoramic glass that wraps around the front to the side. To make that work at a smaller size, the company says the panoramic glass required a slight reduction in thickness and a tighter bend radius, to match the newly shrunken chassis and reduce weight. Havn’s Steven Levitt says the company “could probably claim that it's the tightest bend on any glass panel.” Whether or not you track glass-bend superlatives, the operational point is clear: the company used the shrink to justify a more precise, weight-aware build.

The HS 360 is also not just smaller. It includes upgrades that directly address airflow and build friction, two things that affect both user experience and maintenance. One new feature is a magnetic glass divider that sits above a graphics card using the vertical GPU mount. Havn’s explanation is counter-intuitive: cold air comes up through the bottom of the case in a chimney layout, but a lot of it escapes out the top along the front third. By adding a divider to block some of that escaping path, the company says temperatures are reduced by three degrees.

For anyone thinking about fleets of machines, deskside support, or just the long-term cost of “it’s pretty but annoying,” three degrees can be more than a trivia number. Thermal headroom can affect sustained boost behavior, how hard fans have to work, and how consistently components run during long sessions. The HS 360’s approach is also modular in concept, because the divider is magnetic and positioned to block a specific airflow leak, instead of requiring a redesign of the entire airflow system.

Then there’s the assembly problem that HS 420 owners already know about. In the HS 420, fans need to be installed from inside the case, which becomes a pain once components are already in place. The HS 360 changes that with brackets that let fans be installed from the rear. It also adds convenience for maintenance: the lower three fans can be lifted out from both sides for easier access. These tweaks matter because “easy to build” is one thing when you are assembling fresh. It is a different kind of easy when you are swapping parts, cleaning dust, or updating a GPU.

Havn also targeted a specific kind of motherboard setup that tends to make cable management look worse and planning feel harder: back-connect motherboards. These are boards where connectors sit on the rear for a cleaner front look. The HS 360’s solution is a tray section near the motherboard area that includes cutouts normally used for a 24-pin motherboard cable, and that tray flips around so a back-connect motherboard can fit there without unnecessary cutouts. The result is a cleaner appearance because you can avoid “unused cutout” mess on the chassis.

If the HS 360’s upgrades sound like the kind of quality-of-life improvements people would want on the HS 420 too, that’s because the story is explicitly framed that way. Havn’s Levitt says the company is working on similar updates, but that it’s “something for the future,” implying a possible version update for the larger HS 420. In other words, the HS 360 is the near-term win, while HS 420 owners are effectively waiting to see if those usability and airflow fixes get back-ported.

Pricing, at least for now, is positioned as a small step above the HS 420 and a BF 360 comparison point. Havn says the VGPU version of the HS 360 will be around $230, while the non-VGPU one will be around $160. These are tentative prices, but they suggest a tiering strategy that rewards the vertical GPU mount feature set. For executives and buyers, the key question is whether these changes are strong enough to standardize a new “default” enclosure for performance builds, not just a boutique upgrade for enthusiasts.

At bottom, the HS 360 is Havn trying to win the second-order battle: not just building the case that looks great, but building the case that stays great after assembly, upgrades, and maintenance. If that three-degree thermal improvement, the magnetic divider concept, and the fan access redesign hold up in practice, the HS 360 could become the more operationally friendly version of the HS 420. That is the kind of improvement that makes procurement easier, reduces support friction, and helps teams stop trading looks for usability.
