verdict

The HAVN HS 420 VGPU won’t get a big change from $300, but it offers that it’s a sense of hope and a premium product worth every cent. In this case, the functionality and cooling possibilities are endless, and not building an incredibly clean PC is a huge achievement. Some of its features are a bit cumbersome to use and not the easiest case to work with, but the end result is worth it.

Strong Points

  • Amazing minimalist design
  • Huge single piece, dual side glass panel
  • Great number features
  • Good cooling
Cons

  • Very big
  • Fans not included
  • Some features take time with fiddly
  • Mesh panels promote noise leakage

Things that are relative newcomers in the PC case scene started with Havn’s fuss. Its debut case is the HS 420. This is a premium and extremely stylish case with an impressive wraparound curved glass front panel. That’s Port HS 420 VGPU We’re looking here, and as the name suggests, it’s a variant dedicated to installing graphics cards vertically. It looks unique both inside and outside, dripping with cutting-edge features while potentially large-scale cooling. It all makes the perfect PC case for high-end gaming PCs.

In fact, it’s enough to just win this havn and provide the best PC case guide spot. However, this all comes at a price as there is no major change from $300. However, I don’t think there’s a need for another case. Offering a dedicated vertical GPU version of the case means everything you need to mount the card this way, including PCIE 5.0 riser cables, rotating rear brackets, and angled bottom fan mounts. These are not included in the standard case, but can be used individually if you want to convert them. This is the main reason why the VGPU edition is more expensive than $70.

This case is supported up to E-ATX motherboards, with huge space for expansion when it comes to cooling. Given the price, it could only appeal to people who are already spending $1,000 on a graphics card considerably north. Otherwise, it’s far more important that cash is spent on improving frame rates, processor power, or storage, unless you get the look provided here. To find a place where this expensive case doesn’t justify its price, we paced the cases through this pace to test the quality of the build, ease of installation, cooling and noise.

Features

The HS 420 doesn’t have fans, but it’s not uncommon in high-end cases like this. This is because we expect to add a selection of top quality fans along with some kind of liquid cooling. Whether it’s an AIO cooler or a custom water cooling loop, you don’t need to resort to using a liquid cooler. Liquid coolers and radiators, up to 420mm in size, can be used in up to three locations. This is enough for the most powerful component that can be accommodated in this case.

However, the HS 420 VGPU edition is not for the timid. Because its huge wraparound glass panels and metal structure means it exceeds 19kg (42 lbs) without components included. It is also very large, extending to nearly 55cm (21.6 inches) in length and height. For comparison, more typical ATX cases such as the Corsair 4000D weigh less than 10kg (22 lbs) and are shorter in height and length by 10cm (4 inches).

This case has a total of four exterior panels, with the normal sides and front sections being a single tempered glass bent at right angles. This gives you an unparalleled view of the interior, and the entire section slides with large rollers, giving it a premium feel and helps to deal with the large weight of this panel.

The roof panel is pulled apart by a small material tab at the rear, and also exposes a large removable fan mount, allowing the fan and radiator to fit on the outside of the case. This is much easier. The fur side panels are huge and are completely covered with a series of round rectangular holes that provide a mass of ventilation while giving the case a unique look. This round rectangular shape is repeated throughout several other areas of the case design. The rear panel is also removable, providing a clean look once, providing easy access to the rear fan fitting.

The front panel provides a regular pair of Type A and Single Type C USB ports. This is probably the only standard feature here. For example, the base does not have a case foot. For example, the case sits above a large spacer section with large vents, allowing the fan to breathe the fan mount below. The giant slide out dust filters protect them, but it may be a rare flaw in the case as it is a bit difficult to slide off and feel a bit flimsy.

Cable tidying up and routing is a major feature of the HS 420 VGPU edition, making it easy to build a clean PC. The grommets are in the motherboard tray, but they are not as you normally know. Instead, it has a Louvre-like design that allows cables to pass through without confusing the shape of the grommet. It’s a unique design, but it made me feel a bit crazy to go through the big cables.

On the back, there is also a cable run backed up with clips for anchors and velcro tie, as well as a 6-channel fan controller for amagamate fan cables and controlling them using a single motherboard header. If you need space for some hard disks, you’re lucky as there are 5 3.5s in the internal mount, but these four mean you’ll sacrifice the side fan mount and storage bay.

design

Building a PC on the HS 420 VGPU edition is easy in some respects, but in other respects it is very complicated and time consuming. For example, if you are using a 120mm fan to fit the rear fan, you will need to remove the rear panel and handle the adapter. Usually, you add a few steps to the quick process.

It is also essential to remove the vertical GPU mount and connect the cable to the bottom of the motherboard, and work on cleaning up the cables. There are various screws hidden everywhere in the mount. Thankfully, the process is relatively simple, except for a few compromises when it comes to cooling and cooling and building a PC.

Once built, the PC feels very solid without rattles coming from the panels. There is no push-pin panel like the NZXT H3 flow (it’s not rattle in that case either), thanks to the large one being screwed into place.

Includes GPU support and the vertical mount itself. This can be moved back and forth to accommodate larger graphics cards. The PSU is hidden in the chamber below, with plenty of space for cable storage. An interesting accessory for low fan to install is a glass airflow guide that helps you point the air towards the graphics card. You can see it in particular in the image above.

performance

We do not believe in the usefulness of testing such cases despite fans being sold. Instead, I tested the HS 420 VGPU edition using three 120mm fans. This is a standard supplement that I used in all case tests (unless the case has more fans than this). It also uses a standardized set of test components consisting of an AMD Ryzen 7 9800x3D CPU, 32GB DDR5 6000 RAM, ASUS B850M Plus WiFi motherboard, 1TB Samsung 990 Pro SSD, MSI RTX 5070 TI 16G Ventus 3x Grapher Master Master Master Master Master Master Master Master Hyper Hyper Hyty Hater Hyty Hater Hyper Master Hater Hyper Master Hater Hyper Master Hater Hyper Master Hater Hyper Master Hater Hyper Master Hater Hater Hyper Master Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater Hater C1000 gold power supply.

This case has room for many fans, and is clearly designed to be fitted with three at the bottom, two at the rear, and several more on the roof. However, the case worked well even when only three fans were mounted on the roof, rear and base. The case fan was at full speed, the CPU reached 76°C and the GPU reached 69°C.

The CPU numbers are actually slightly higher than using three fans on a much smaller NZXT H3 flow. However, in that case, one of the fans will blow air directly into the CPU cooler. The HS420 doesn’t have much direct airflow to the CPU. The GPU, on the other hand, is a 2°C cooler than the H3 flow, indicating how well the GPU airflow configuration works in this case. It is also worth repeating that in this large case there are only three fans.

The core cooling capacity of this case is emphasized by the fact that if you reduce the fan speed to 50%, the CPU temperature will only rise by 1°C.

However, one thing to note in this case is that, despite the large curved glass panels occupying two sides, they do not benefit from fans running at lower speeds. The fan measures the sound level at 53DBA at 100% speed, but if the fan is at 50% this has dropped to 50DBA. You’ll really want to make sure you fill those fan mounts and run the fans wonderfully and slowly.

price

The HAVN HS 420 VGPU edition costs $300, which is a huge amount to pay for any kind of case, but this is a very well-made case with some serious premium touches, such as the front of the wraparound glass. Additionally, the non-overturned GPU version is significantly cheaper, at $230. So you need a Coalk in this case and don’t mind getting a vertical GPU mount. Or, if you’re happy to buy separately later, there are more affordable options.

However, another factor is that this case is a very blank slate designed to spend hundreds more dollars kitting out along with fans and other cooling components.

At this price, aesthetics also begin to play an important role, and competitive design can somehow shake you up. The Hyte Y70 and its touch version are also clear candidates. Quietly! It also has a light base 900 FX, which appeals to RGB lighting fans. This is the opposite of Phanteks NV. However, the HS 420 feels it is worth the $300 asking price compared to it.

verdict

If you’re spending $300 on a PC case, you should seriously consider the HAVN HS 420 VGPU. This ultra-stylish case combines innovative design with amazing build quality to make it the perfect home for high-end systems. That cable routing is some of the best and elaborate things we’ve seen, with plenty of cooling possibilities, and even space for many hard disks without much compromising the support of fans and radiators.

However, it’s not an easy case to build, so if you want to run in just a few hours, it probably isn’t. This is a weekend project that is more suitable for high-end water cooling systems and the complexities involved in setting up such systems.

It’s not a case that you’re ready to leave the box either. You need to consider your own fan and its porous design allows for very low airflow restrictions and great cooling, but that means that if you are sensitive to noise, you need quiet hardware. For your first effort, the HAVN HS 420 is stunning, but given your options, choose the standard model in the VGPU edition to save cash and simplify the build process.
