This article covers LIANLI ミドルタワーPCケース LANCOOL 217 BLACK ファン5基標準搭載 背面コネクタ対応（ATX.

Overview

LIAN LI's LANCOOL 217 BLACK is a mid-tower PC case that comes with five pre-installed fans, making it a strong contender for builders who prioritize airflow right out of the box. The front features two 170mm fans with a 30mm thickness, complemented by two 120mm fans at the bottom and a 140mm fan at the rear. This configuration delivers substantial cooling capacity for high-performance components. Beyond raw fan count, the case supports back-connect motherboards (ATX and Micro ATX), allowing for cleaner cable management and a more polished interior look. The tool-less fan mounting system lets you switch between CPU-focused and GPU-focused cooling modes in seconds, giving builders flexibility without extra hardware. Positioned in the mid-range segment, the LANCOOL 217 offers a compelling balance of features and price.

Compatibility Guide

The LANCOOL 217 supports a wide range of motherboard form factors: SSI-EEB (up to 330mm wide), E-ATX (up to 280mm wide), ATX, Micro ATX, and Mini-ITX. Notably, it is compatible with back-connect motherboards from ASUS (BTF series) and MSI (Project Zero series), making it a future-proof choice for clean builds. Power supply installation is bottom-mount, with the option to orient the PSU horizontally for easier cable routing or vertically in the traditional position. Before purchasing, verify your GPU length and CPU cooler height against official specifications to ensure a proper fit.

Product Info

The LANCOOL 217 BLACK was released in 2025 and is available exclusively in black. It is constructed from steel and weighs approximately 9.25 kg. The retail price on is around ¥20,320 (tax included). In terms of market positioning, this case sits comfortably in the mid-range tier. The inclusion of five pre-installed fans—including two thick 170mm units—sets it apart from many competitors that ship with only one or two basic fans.

Best Use Cases

For gamers building a new rig, the LANCOOL 217 is an excellent choice. The high-volume front fans ensure that even a powerful GPU and CPU stay cool under load, while the tool-less fan mounting allows you to prioritize either CPU or GPU cooling depending on your build. Enthusiasts who want to experiment with back-connect motherboards will find this case particularly appealing. The ability to route cables behind the motherboard tray results in a remarkably clean interior, ideal for showcase builds with tempered glass side panels.

Things to Consider

The 170mm front fans are 30mm thick, which is a non-standard size. If you plan to replace or add fans later, be aware that compatible alternatives may be limited compared to standard 120mm or 140mm fans. E-ATX motherboard support is limited to boards 280mm wide or less. Full-size E-ATX boards (305mm wide) will not fit, so check your motherboard dimensions carefully. While the horizontal PSU orientation simplifies cable management, some longer power supply units may interfere with the drive cage or other components. Measure your PSU depth before finalizing the build. ## Alternatives
In the same price bracket, the Fractal Design Pop Air and Cooler Master MasterBox NR600 are direct competitors. The Pop Air offers a clean, minimalist design with three pre-installed fans, but lacks back-connect motherboard support. The LANCOOL 217 pulls ahead with five fans and that key compatibility feature. The MasterBox NR600 provides good expansion options but ships with only one fan, requiring additional purchases for optimal airflow. If you want a case that delivers strong cooling performance without extra spending, the LANCOOL 217 is the more complete package.
