The Lian Li Vector V100 is a mid-tower ATX PC case offering that manages to deliver on the quality and features that one would expect of a Lian Li product offering, despite its wallet-friendly price tag of just US$54.99.

The Lian Li Vector V100 is a budget-friendly mid-tower PC case that captured the attention of the tech media when it was first showcased at Computex 2025 in May this year, all thanks to its wallet-friendly price tag of just US$54.99. For that price, you get a fish tank-style mid-tower ATX case with two tempered glass side panels, and the Lian Li badge on the bonnet no less.

Available in black or white, the V100 features a unique aesthetic with a "stepped" gradient on the side panel, with an illuminated ARGB LED strip thrown in for good measure -  it's also available in the V100R variant that comes with four pre-installed 120mm case fans. Read on to learn more about the Vector V100, and to see it in action as part of a demo build that also utilises Lian Li's new budget-friendly case fans - the Uni Fan CL Wireless 120mm ARGBs!

Packaging & Accessories

The Vector V100 ships in a run-of-the-mill brown cardboard box with your usual product illustrations and descriptions on all sides.

In terms of accessories, the Vector V100 comes with an instruction manual as well as a single box of accessories. Within the box of accessories, we get a thank you note, a whole bunch of screws, cable ties, rubber grommets for 3.5” hard disk mounting purposes, spare friction clips for the panels of the case, as well as the necessary hardware for the GPU support bracket that Lian Li's included with the case.

Within the manual, we get illustrations on how best to do cable management with the V100. While the illustrations aren’t the most complicated (seeing as cable management with this case isn’t rocket science anyway), it’s still something that's much appreciated in my book.

Exterior Walkthrough

For this review, Lian Li’s sent over the white variant of the V100 that doesn’t come with any preinstalled fans, where it's also known as the V100W (the black variant is called the V100X).

The case features a traditional mid-tower ATX layout with a chamber at the bottom for your power supply and a storage drive, and is made of a combination of steel and plastic and two tempered glass panels - the tempered glass panels offer an unobstructed view of your PC hardware components.

The left side panel features an interesting gradient design, with a plastic bottom border featuring some aesthetic grooves for good measure, as well as an illuminated ARGB lighting strip that runs along the said border on the inside of the case – we’ll take a closer look at this ARGB LED strip later in this review. In my opinion, this gradient aesthetic certainly lends the V100 a unique look that helps it stand out from amongst the competition.

As you might have surmised, the front panel connectors of the case are located on the left side panel, right below the lower edge of the tempered glass side panel. We get two USB 3.0 Type-A ports, a USB 3.1 Gen 2 Type-C port, a 3.5mm microphone and headphone combo jack, a reset button as well as a power button. Do note that the case does not come with a hard disk activity indicator light!

The other side panel of the V100 is a simple steel panel with ventilation openings right above where the side intake fan openings would be, and I guess it’s no coincidence that the ventilation openings form the shape of the alphabet “L”, which is a nice aesthetic touch.

The top panel of the case is basically one huge ventilation opening for the cooling hardware that you’d be installing up top, be it fans or an AIO radiator, where it comes with an integrated dust filter.

Over on the bottom panel of the V100, we get ventilation openings for the power supply unit’s cooling fan, where Lian Li has also included a removable dust filter. As can be seen, the case comes with four plastic feet with foam-like inserts. 

The rear of the case is a pretty standard affair with lots of ventilation openings, and the expansion slot covers are of the reusable variety, which is definitely a plus point for more budget-oriented PC case offerings. Another plus point? The expansion slot covers actually use thumbscrews instead of normal screws, which is great to see.

Getting the panels off the Vector V100's cakewalk, as Lian Li’s gone with a tool-less design for all of the case's panels, and they can be pried off very easily from the chassis with just a wee bit of elbow grease. As mentioned earlier, we get a dust filter with the top panel, where unfortunately, it’s the sort that’s integrated into the panel and isn't intended for removal by end-users.

The dust filter of the power supply unit’s cooling fan on the other hand, slides in and out of place easily, as pictured above.

Cooling Hardware Support

As mentioned earlier, Lian Li shipped over the variant of the Vector V100 that doesn't come with any pre-installed case fans. In this regard, the side panel of the case has ventilation openings that support up to three 120mm fans – do note that due to space constraints, you won’t be able to mount a 360mm radiator on the side panel.

Over on the top panel, we get support for either two 140mm case fans, three 120mm case fans or up to a 360mm AIO radiator with a height of no more than 180.5mm. 280mm AIO radiators are also supported on the top panel.

On the bottom panel right above the chamber where your power supply unit would be installed, we get support for up to two 120mm case fans.

Finally, over on the rear panel, the Vector V100 comes with a single ventilation opening that supports either a 140mm or 120mm case fan.

Physical Dimensions & Clearances

The Vector V100 has pretty average dimensions for a mid-tower ATX PC case, where it measures in at 446mm (L) x 484.65mm (H) x 235.5mm (W).

For you folks intending to use an air cooler for your processor, do note that the case supports CPU coolers of heights no more than 178mm, according to the spec sheet for the V100.

For your graphics card, the case supports horizontal GPU mounting only, and comes with support for graphics cards with lengths of up to 420mm.

As part of the V100, Lian Li's included a GPU support bracket that can be mounted on the motherboard tray, where it comprises the pieces of hardware as pictured above.

To utilise the included GPU support bracket, you’ll first have to install your motherboard and thereafter, use the included bracket posts in lieu of the motherboard screws for the screw hole openings shown above.

With that done, secure the GPU bracket rail to the posts, mount the bracket onto the rail with the included screw and washer, and you’re good to go.

It's worth mentioning that I did discover a snag with the GPU bracket as I went about installing the graphics card I that I intended to use for the demo build with the V100 - the GPU bracket couldn't be secured tightly to the mounting rail due to spatial constraints. As illustrated by the photo above, the screw that secures the bracket to the mounting rail protrudes as you tighten the bracket to the said rail, where as a result, it’d get into contact with the M.2 heatsink of the ASUS ROG STRIX Z790-A GAMING WIFI II motherboard that I used for the build. This prevented me from using the GPU bracket properly, as it would shift with the weight of the graphics card, and I wound up using a third-party GPU support bracket instead. Just something for you folks to take note of if you’re intending to use the included GPU support bracket and if your motherboard has aM.2 heatsinks or other potential obstructions where the support bracket rail would be installed!

Moving on to the motherboard tray, the Vector V100 comes with support for motherboards with rear connectors, so motherboards from say, ASUS’s BTF line-up, Gigabyte’s Project Stealth series or MSI’s Project Zero line-up will be compatible with this case.

In terms of power supply dimensions, Lian Li indicates that the Vector V100 has 220mm of length clearance for a power supply, which is mounted in the bottom chamber of the PC case.

Finally, one interesting feature that the Vector V100 comes with is a "platform" that allows you to display a figurine of choice – I guess this plays into the trend of blind box figurines, so if you have a coveted Labubu that you’d like to showcase, you can place it on this very display platform in the V100 – to do so, you’ll have to remove a plastic cover first that’s held in place by a single screw.

Storage Drive Support

For those of you intending to install 2.5” and 3.5” drives for your PC build with the V100, Lian Li has included a drive bracket on the rear of the motherboard tray that supports a single 2.5” SSD, as well as a drive mount in the bottom chamber of the case for a single 3.5” hard drive.

Building a PC with the Lian Li Vector V100

The front panel connectors of the case are a pretty straightforward affair, where we get the usual front panel USB 3.0 Type-A connector, a USB 3.1 Gen 2 Type-C connector, a front panel audio connector as well as a nine-pin front panel connector for the power button and reset button. I appreciate the fact that Lian Li has opted to use a nine-pin connector rather than standalone connectors, which can be more fiddly to hook up to their respective header pins on the motherboard.

Seeing as the Vector V100 comes an illuminated ARGB strip along the edge of the bottom panel, we get a corresponding 5V ARGB connector that can be daisy-chained to other 5V ARGB devices for cable management purposes.

For the demo build that I'll be doing up with the Vector V100, I'll be using an ASUS ROG STRIX Z790-A GAMING WIFI II motherboard, which is an ATX form-factored motherboard on the Intel LGA1700 platform. Getting said motherboard into the case was pretty easy, where the motherboard standoffs are already pre-installed on the motherboard tray, and we've got ample space for manoeuvring things around.

Installing the power supply unit was a cinch too, just make sure that you’ve got a PSU that’s no more than 220mm in length and you're good.

For this demo build, I’ll be installing Lian Li’s new UNI FAN CL WIRELESS 120 case fans, which are a great accessory to go with the Vector V100, seeing as both products are targeted at budget-conscious consumers. The Uni Fan CLs are Lian Li’s new wallet-friendly offerings in their case fan line-up, and feature support for Lian Li’s proprietary L-Wireless ecosystem as well as the L-Connect 3 app.

The Wireless CL fans come with subtle ARGB LED strips along the edges of the fan frame, which is a nice touch, and we’ll see them in action later in this review. They also feature the Uni Fan interlocking system, where you’ll first have to flip out two plastic fan buckles and thereafter, position the fans accordingly before snapping them into place.

As can be seen in the photos above, I've gone with triple normal-blade Wireless CL fans for the top panel, where they'll serve as exhaust fans, and triple reverse-blade fans for the side panel, where they'll act as intake fans.

Rounding things off in the fan orientation section, I have two reverse-blade Uni Fan CLs installed on the bottom panel as intake fans, and a normal-blade variant installed on the rear panel for rear exhaust fan duty.

The graphics card for this demo build’s a Gigabyte GeForce RTX 4090 AERO OC 24G, where it measures in at 342mm x 150mm x 75 mm, and fits very easily into the case.

Moving things along, and with the demo build nearly completed, it’s a good time to talk about cable management. The Vector V100 comes with all the expected openings in the right places for cable management purposes, where we get large openings on motherboard tray and on the bottom panel of the case with which to route all necessary cables through.

Over on the rear, it’s great to see that Lian Li’s also included plastic clips along one of the edges of the V100 to further help with cable routing.

While I didn’t put in a whole amount of effort to cable manage with this demo build, I think it still looks pretty decent all things considered!

Completed Demo Build Aesthetics

Thermal Performance

To benchmark the thermal performance of the Lian Li Vector V100 PC case, I put together a demo build with the following specifications:

• CPU: Intel Core i5-14600K (stock "ASUS Advanced OC Profile")
• CPU Cooler: Cooler Master Hyper 622 Halo White
• CPU Thermal Paste: Cooler Master CryoFuze
• Motherboard: ASUS ROG STRIX Z790-A GAMING WIFI II
• Memory: 32GB (2x16GB) KingBank DDR5 SoarBlade RGB DDR5 6000 CL30
• Graphics Card: Gigabyte GeForce RTX 4090 AERO OC 24G
• PSU: Cooler Master MWE Gold 1050 V2 ATX 3.0
• Case: Lian Li Vector V100 White
• Case Fans: 4x Lian Li Uni Fan CL Wireless Normal Blade, 5x Lian Li Uni Fan CL Wireless Reverse Blade
• OS: Microsoft Windows 11 Pro (24H2 with all latest updates installed)
• Fan Curve: Stock standard profiles

With F1 23’s in-game benchmark, where I ran a five-lap test for around nine minutes in total, the Core i5-14600K processor in the demo build achieved an average CPU package temperature of around 59.0°C, while the RTX 4090 AERO OC 24G achieved an average GPU temperature of 69.7°C, an average GPU memory junction temperature of 75.1°C and an average GPU hot spot temperature of 80.8°C.

These results were achieved in a non air-conditioned room with a temperature of around 31.5°C - a pretty decent set of results I must say, considering that the demo build was tested in a non-air-conditioned room that was pretty warm (thank you global warming). For the benchmark test, the fan curves were left on their stock settings without any tweaks, and ran at a speed of around 1347rpm during testing.

Conclusion & Pricing

To sum up, I think that the Lian Li Vector V100 delivers on its value proposition as a budget-friendly fish-tank style PC case. Despite its price tag, it still manages to deliver on the build quality and features that one would come to expect from a Lian Li PC case. Fit and finish is good, I really like the aesthetic of the V100 especially with the gradient design and the integrated ARGB LED strip, and thermal performance is decent as well. Perhaps the only minor niggle I have with this case is the included GPU support bracket, where I wasn’t really able to use it in my demo build due to spatial restrictions, which were brought about by the choice of motherboard that was used.

In terms of pricing, the Vector V100 has a MSRP of US$54.99 for both the black and white variants without any preinstalled fans. For the variant with four preinstalled fans (the V100R), it has a MSRP of US$74.99.
