This article covers LIANLI 背面コネクタ対応ミドルタワーPCケース LANCOOL 217 INF ホワイト インフィニティミラーフロントパネル SSI-EEB (幅330mm以下).

Overview

The Lian Li LANCOOL 217 INF is a mid-tower PC case that brings together clean aesthetics and practical airflow. Its standout feature is the infinity-mirror front panel, which creates a mesmerizing depth effect with ARGB lighting. This case is also designed to support reverse-connector (BTF) motherboards, allowing for nearly cable-free builds. With three pre-installed ARGB fans — two 170mm at the front and one 140mm at the rear — you get excellent cooling right out of the box.
Despite being a mid-tower, the LANCOOL 217 INF supports large motherboards up to SSI-EEB (330mm wide) and E-ATX (280mm wide). The I/O panel can be repositioned from the top to the bottom of the front bezel, giving you flexibility for desk placement. This case targets enthusiasts who want a clean, cable-managed build without breaking the bank.

Product Info

The LANCOOL 217 INF is a mid-range case introduced by Lian Li in 2024. Priced around $130-150 (¥20,000-¥22,000), it offers premium features like an infinity-mirror front panel, full ARGB fans, and reverse-connector compatibility at a competitive price. It targets builders who want a tidy, visually striking system without the premium of flagship cases. The included fans and flexible radiator support make it ready for most mid-range to high-end builds.

Best Use Cases

  • Cable-management perfectionists: Pairing this case with a BTF motherboard virtually eliminates visible cables. Perfect for builders who obsess over the inside of their case. Check motherboard compatibility first.
  • High-airflow gamers: The large 170mm front fans move significant air quietly. Suitable for high-TDP CPUs and GPUs like an RTX 4080 and Core i7-14700K.
  • Desk‑space optimizers: The movable I/O panel allows you to route cables from the top or bottom, adapting to monitor arms or tight desk setups.

Things to Consider

Before buying, note that the 170mm front fans are non‑standard — replacing them is difficult, so you are stuck with the stock fan performance and noise profile. Also, E-ATX support is limited to boards 280mm or less in width, ruling out wide workstation boards. Because this case is designed around reverse‑connector motherboards, the cable space behind the motherboard tray is optimized for that layout; with a standard ATX board, you may find cable routing slightly less tidy than a dedicated non-BTF case. Finally, while the price is attractive, there are competing cases like the Fractal Pop Air or Corsair 4000D that offer more traditional layouts but less flashy front panels.

FAQ

Q: Can I use a standard ATX motherboard without reverse connectors?
A: Absolutely. The case works with any ATX, Micro ATX, or Mini-ITX motherboard. The BTF support is an added option, not a requirement.
Q: What radiator sizes fit at the top?
A: Top panel supports 240mm and 280mm radiators. Check clearance with motherboard VRM heatsinks and memory modules.
Q: How does this compare to the standard LANCOOL 217?
A: The INF version upgrades the front panel to an infinity mirror design and includes ARGB fans instead of standard ones. Otherwise they share the same layout and compatibility. If you prefer a simpler look, the non-INF version is slightly cheaper.
