Lian Li vs Rosewill Case Comparison
Motherboard support
Both cases accommodate ATX motherboards, but their expansion capabilities differ. The Rosewill Helium NAS explicitly supports E-ATX boards, offering more room for high-end workstation or enthusiast motherboards. The Lian Li Lancool 205 Mesh supports ATX, Micro ATX, and Mini-ITX sizes. It does not list E-ATX compatibility in its specifications. If you plan to use a large E-ATX motherboard, the Rosewill provides the necessary clearance. For standard ATX or smaller form factors, both cases work, but the Lian Li offers more flexibility for Mini-ITX builds.
Side panel material
The visual appeal and internal visibility depend on the side panel material. The Lian Li Lancool 205 Mesh features a tempered glass side panel. This allows you to see your components and lighting clearly. The Rosewill Helium NAS uses an all-mesh side panel design. This prioritizes airflow over visibility. If you want to showcase your hardware or RGB lighting, the Lian Li is the better choice. If you prefer maximum air intake and do not care about seeing inside, the Rosewill mesh panel serves that purpose well.
Included fans
Stock fans affect initial cooling performance and noise levels. The Rosewill Helium NAS comes with four 140mm PWM fans. Larger fans generally move more air at lower speeds, potentially reducing noise. The Lian Li Lancool 205 Mesh includes three fans: two 140mm front fans and one 120mm rear fan. While the Lian Li has a similar front intake setup, the Rosewill adds an extra fan. This gives the Rosewill a slight advantage in stock airflow volume. You may need to add more fans to the Lian Li to match the Rosewill's airflow capacity.
Lighting features
RGB lighting is a key feature for many builders. The Lian Li Lancool 205 Mesh includes ARGB (Addressable RGB) PWM fans. It also has a C/M button on the top panel for direct control of lighting modes and colors without software. The Rosewill Helium NAS specifications do not mention any RGB lighting or ARGB support. It focuses on functional cooling rather than aesthetics. If you want customizable lighting effects and easy manual control, the Lian Li is the clear winner. The Rosewill is purely functional in this regard.
Connectivity
Front panel connectivity determines how easily you can access modern devices. The Rosewill Helium NAS features a USB 3.2 Type-C port on the front panel. This allows for fast data transfer speeds with compatible devices. The Lian Li Lancool 205 Mesh lists 2x USB 3.0 ports, audio jacks, and power buttons. It does not list a Type-C port in its I/O essentials. If you frequently connect USB-C devices like modern phones or SSDs, the Rosewill offers greater convenience and speed. The Lian Li relies on traditional USB 3.0 connections.
Storage capacity
Storage options vary based on case design. The Rosewill Helium NAS is designed for home servers, supporting up to 10 x 3.5-inch HDDs and 3 x 2.5-inch SSDs. This massive capacity suits data-intensive applications. The Lian Li Lancool 205 Mesh mentions removable SSD mounting brackets and a bottom side panel PSU and HDD bay, but does not specify the exact number of drive bays. For users needing extensive drive space for media libraries or backups, the Rosewill provides a dedicated solution. The Lian Li appears more focused on component cooling than bulk storage.
Which Case Fits Your Build
Gamer wanting RGB and glass
Choose the Lian Li if you want visible RGB lighting. It includes three pre-installed ARGB fans and a tempered glass side panel for showcasing components. The top I/O panel offers a dedicated button to cycle through seven lighting modes. This case prioritizes aesthetics and direct control over fan effects for your gaming setup.
Home server builder needing storage
Select the Rosewill Helium NAS for heavy storage needs. It supports up to ten 3.5-inch HDDs and three 2.5-inch SSDs, making it ideal for media libraries or virtual machines. The all-mesh design ensures unrestricted airflow to keep drives cool. This chassis focuses on capacity and thermal management for data-intensive applications rather than visual flair.
User needing E-ATX support
Pick the Rosewill if your motherboard is E-ATX. The Lian Li only supports ATX, Micro ATX, and Mini-ITX sizes. The Rosewill Helium NAS explicitly accommodates larger E-ATX boards. This extra space allows for high-end workstation configurations. If you plan to install a larger motherboard, this case provides the necessary physical compatibility and internal clearance.
