Choosing between the NZXT H510 and the Lian Li A3-mATX is a decision that comes up repeatedly among UK PC builders who want a clean, well-ventilated mid-tower without spending a fortune. The H510 has been a staple recommendation for years thanks to its minimalist steel-and-tempered-glass aesthetic and straightforward cable management, while the Lian Li A3-mATX arrived more recently to challenge it with a mesh-forward design, superior out-of-the-box airflow, and a competitive price point. Since last year, Lian Li updated the A3 with revised fan mounting positions and improved front-panel connectivity, making the comparison even more relevant for 2024 builders. This article is aimed at first-time builders, upgraders stepping up from budget cases, and enthusiasts who want tidy looks without sacrificing thermal headroom. We cover five closely matched cases in this category so you can find the right fit for your budget, form factor, and cooling ambitions.
Quick Verdict
Best Overall: Lian Li LANCOOL 216 RGB, which balances airflow, build quality, and value better than almost anything else at its price point in the UK market right now.
Best Value: Lian Li A3-mATX, which undercuts the H510 on price while delivering noticeably better thermal performance thanks to its mesh front panel.

How We Picked
Our selection process for this comparison focused on cases that are currently available through UK retailers at competitive prices, with a particular emphasis on the mid-tower segment where the NZXT H510 and Lian Li A3-mATX are most commonly compared. We evaluated each case against five core criteria: thermal performance based on published benchmark data and independent testing, build quality assessed through hands-on inspection and long-term user feedback, value for money relative to included accessories and features, ease of build considering cable management, fan installation, and component clearances, and front panel connectivity reflecting current standards. Cases with known quality control issues or discontinued product lines were excluded. We also considered the practical needs of UK builders, including availability from major UK retailers and compatibility with components commonly sold in the UK market. Pricing was verified at the time of writing but may vary.
Buying Guide
Airflow vs Aesthetics
The single most important decision when choosing between the H510 and A3-mATX, or any of the cases in this comparison, is how you weigh airflow against appearance. Cases with solid or semi-solid front panels like the original NZXT H510 look cleaner on a desk but restrict intake airflow significantly. This is not a problem for mid-range builds with a Ryzen 5 or Core i5 and a GPU in the RTX 4060 class, but it becomes a genuine concern once you move to higher TDP components. If you are pairing your case with a Ryzen 7 7700X or Core i7-14700K and a GPU above the RTX 4070 tier, a mesh front panel is strongly advisable.
Form Factor Compatibility
The Lian Li A3-mATX only supports mATX and Mini-ITX motherboards, which is a hard limitation. Before purchasing, confirm that your chosen motherboard fits. The NZXT H510, H510 Flow, LANCOOL 216 RGB, and Pure Base 500DX all support full ATX, giving you more flexibility for future upgrades. If you are building on a budget mATX platform and do not anticipate upgrading to a full ATX board, the A3-mATX is an excellent choice. If there is any chance you will want a larger motherboard in the future, opt for a full ATX-compatible case.
Included Fans and Upgrade Costs
The number and size of included fans has a direct impact on the total cost of your build. The H510 and H510 Flow include two 120 mm fans, which are the minimum for adequate airflow in most builds. Adding a third fan to either case will cost between £10 and £30 depending on the model. The A3-mATX includes two 140 mm ARGB fans, which is a better starting point. The LANCOOL 216 RGB includes three 160 mm ARGB fans, which is exceptional value and means most builders will not need to purchase additional fans at all. Factor these costs into your total budget when comparing prices.
CPU Cooler Clearance
If you are planning to use a large air cooler such as the Noctua NH-D15 or be quiet! Dark Rock Pro 4, check the CPU cooler height limit carefully. The A3-mATX's 155 mm limit rules out several popular tall coolers. The H510 and H510 Flow allow up to 165 mm, which covers most dual-tower designs. The Pure Base 500DX's 190 mm limit is the most generous in this comparison and suits builders who want maximum air cooling headroom.
Front Panel Connectivity
USB-C front panel ports are now standard across all five cases in this comparison, but the speed of the connection varies. USB 3.1 Gen 1 (5 Gbps) is adequate for most peripherals, while USB 3.2 Gen 2 (10 Gbps) is preferable if you regularly transfer large files to external SSDs. Check your motherboard's front panel header specifications as well, since a USB 3.2 Gen 2 front panel port requires a matching header on the motherboard to operate at full speed.
Dust Management
Mesh cases offer better airflow but accumulate dust more quickly than cases with solid panels. The be quiet! Pure Base 500DX addresses this with a magnetic front dust filter, which is the most practical solution in this comparison. If you choose a fully open mesh case like the A3-mATX or LANCOOL 216 RGB, plan to clean the interior every four to six weeks in a typical home environment, or more frequently if you have pets.
Final Verdict
After comparing all five cases across airflow, build quality, value, and practical usability, the Lian Li LANCOOL 216 RGB is the overall winner. Its three included 160 mm ARGB fans deliver class-leading out-of-the-box thermal performance, the hinged tempered glass panel is a genuine quality-of-life improvement over screw-retained designs, and the generous component clearances make it suitable for high-end builds that will last several upgrade cycles. For mATX builders on a tighter budget, the Lian Li A3-mATX remains the Best Value pick, offering superior airflow to the H510 at a comparable or lower price. The NZXT H510 retains its place as a solid choice for mid-range builds where aesthetics and cable management are the priority, but builders who care about thermals should look at the H510 Flow at minimum, or step up to one of the Lian Li options for best results.
Frequently Asked Questions
The H510 is adequate for mid-range builds using components such as a Ryzen 5 or Core i5 paired with an RTX 4060 or RX 7600. For higher TDP components like a Ryzen 7 or RTX 4070 and above, the restricted airflow from the solid front panel becomes a limitation. Adding a third fan and considering an aftermarket mesh front panel mod will help, but at that point a case with a native mesh front panel such as the H510 Flow or Lian Li A3-mATX is a more straightforward solution.
No, the Lian Li A3-mATX is designed exclusively for mATX and Mini-ITX motherboards. Full ATX boards are too large for the chassis. If you need ATX support with similar Lian Li airflow credentials, the LANCOOL 216 RGB is the recommended alternative and is available at a higher but still competitive price point.
The A3-mATX is generally quieter under load despite its better airflow, because its two included 140 mm fans can move the same volume of air at a lower RPM than the H510's 120 mm fans working harder against a restricted front panel. For the quietest overall experience in this comparison, the be quiet! Pure Base 500DX with its three 140 mm Pure Wings 2 fans is the standout choice.
For mid-range builds, both cases are usable with their included fans. The H510's two 120 mm fans are the more limiting of the two, and a third rear or top exhaust fan is a worthwhile addition for any build above the RTX 4060 tier. The A3-mATX's two 140 mm fans provide better baseline coverage, though a third fan is still beneficial for demanding components. The LANCOOL 216 RGB's three 160 mm fans are sufficient for most high-end builds without any additions.
The primary difference is the front panel design. The standard H510 uses a solid steel front panel that significantly restricts intake airflow, while the H510 Flow replaces this with a perforated mesh panel that improves airflow by a meaningful margin. The H510 Flow also includes a USB 3.1 Gen 2 Type-C port compared to the standard H510's Gen 1 port. Both cases share the same interior dimensions, fan mounting positions, and cable management system, so the choice comes down to whether the improved airflow justifies the small price premium.
