Lian Li vs Okinos Case Specs
Motherboard Support
The Lian Li Lancool 205 Mesh is a mid-tower chassis that supports ATX, Micro ATX, and Mini-ITX motherboards. This broad compatibility allows you to build with larger standard boards. The Okinos Aqua 3 is a micro ATX case. It only supports MATX and ITX motherboards. You cannot install a standard ATX board in the Okinos. If you need the extra space for larger graphics cards or CPU coolers that come with ATX boards, the Lian Li is the better choice. The Okinos is strictly for smaller form factor builds.
Tower Size
Size matters for component clearance and overall footprint. The Lian Li Lancool 205 Mesh is a mid-tower with dimensions of 29.2 inches in length, 11.6 inches in width, and 29.2 inches in height. It weighs 15.5 pounds. The Okinos Aqua 3 is a compact micro ATX case. It measures 13.8 inches in length, 8.27 inches in width, and 15.4 inches in height. It weighs only 9.19 pounds. The Okinos is significantly smaller and lighter. The Lian Li offers more interior volume for larger components.
Fan Size
Fan size affects cooling performance and noise levels. The Lian Li Lancool 205 Mesh comes with three pre-installed fans. It includes two 140mm fans at the front and one 120mm fan at the rear. Larger fans can move more air at lower speeds. The Okinos Aqua 3 comes with three pre-installed fans as well. However, all three are 120mm fans. Two are located at the top and one is at the rear. The 140mm fans in the Lian Li provide a potential advantage in airflow capacity compared to the 120mm fans in the Okinos.
Connectivity
I/O options determine how you connect peripherals. The Lian Li Lancool 205 Mesh provides two USB 3.0 ports, audio jacks, and a power button on the top panel. It does not list a USB Type-C port in its specifications. The Okinos Aqua 3 offers more modern connectivity. It includes two USB 3.0 ports, audio jacks, and a USB Type-C 3.2 Gen 2 port. The Type-C port supports 10Gbps data transfer speeds. If you need high-speed data transfer via Type-C, the Okinos has the clear advantage.
Side Panel
Both cases feature tempered glass side panels to showcase your internal components. The Lian Li Lancool 205 Mesh has a single tempered glass side panel. The Okinos Aqua 3 takes a different approach with a panoramic design. It features fully glass-covered front and side panels. This creates a 270-degree wide-angle view of your hardware. The Okinos offers a more extensive glass display area. The Lian Li provides a standard single-panel view. Both use tempered glass for durability and clarity.
