Lian Li LANCOOL 217 ATX Mid-Tower PC Case, 5 PWM Fans, Black Walnut Wood

Builders wanting strong cooling straight out of the box will appreciate the Lian Li LANCOOL 217 ATX mid-tower PC case. Instead of requiring you to buy extra case fans separately, it arrives equipped with five pre-installed fans: two large 170x30mm intake units at the front, two 120mm reversed-blade fans, and a 140mm exhaust fan at the rear. This setup generates ample air movement across internal hardware right from day one, helping your processor and graphics card maintain lower operating temperatures during intensive tasks.

Airflow customization is another strong point of this chassis. The front intake bracket features toolless fan mounting and adjustable positioning. By default, the twin 170mm fans sit in a balanced orientation that provides equal cooling for both the graphics card and the processor. If your primary concern is processor heat, you can raise both front fans into CPU mode, directly targeting incoming fresh air toward the upper portion of your motherboard and cooler for increased efficiency.

Aesthetic design goes beyond standard sheet metal and plastic by incorporating real wood accents on the exterior. This model features dark walnut, giving the mid-tower a warm, furniture-like appearance that integrates smoothly into home offices and modern living spaces. In addition, Lian Li designed the interior to support back-connect motherboards. Routing primary motherboard connections behind the tray keeps wiring hidden from sight, ensuring clean internal visuals while simultaneously removing clutter that could disrupt incoming airflow.

Internal flexibility extends to the power supply bay, which accommodates units up to 220mm in length. You can mount your power supply facing forward or rotate its orientation to simplify wiring runs based on your chosen components. Lian Li also added dual power buttons on the chassis exterior, giving you quick and convenient reach whether you place the tower on top of your desk, underneath it, or positioned to your left or right.

As for limitations, hardware compatibility requires some attention during planning. While the power supply chamber handles models up to 220mm long, exceptionally large enterprise or specialized power units may exceed that measurement. Furthermore, the prominent natural walnut trim provides a distinct look that might not match every aesthetic, especially if you prefer an industrial all-metal workspace.

Verdict: The Lian Li LANCOOL 217 ATX mid-tower PC case is a capable, well-ventilated enclosure suited for builders who want comprehensive out-of-the-box fan coverage and refined exterior styling. If you plan to build with standard ATX parts or back-connect hardware and appreciate natural walnut accents, it serves as an excellent foundation for your next personal computer build.

• Form Factor: ATX Mid-Tower
• Pre-Installed Fans: 5 (two 170x30mm front, two 120mm reversed-blade, one 140mm rear)
• Fan Control: PWM
• Accent Material: Real Black Walnut wood
• Maximum PSU Length: 220mm
• Motherboard Compatibility: Supports back-connect motherboards
• Power Controls: Dual power buttons

A great fit if you:

• Want a complete cooling solution out of the box without needing to purchase additional case fans.
• Plan to assemble a tidy build using a modern back-connect motherboard to conceal your power cables.
• Prefer the organic look of natural dark walnut wood accents over purely plastic or industrial metal enclosures.
• Appreciate convenient physical controls such as dual power buttons that accommodate varied desk and floor placements.

Consider something else if you:

• Need an enclosure capable of housing specialized or oversized power supplies exceeding 220mm in total length.
• Prefer a strictly utilitarian, all-metal aesthetic without decorative natural wood elements.

Confirm on the listing:

• Check whether your chosen power supply unit measures 220mm or less in length to guarantee proper fitment inside the lower chamber.
• Check whether your motherboard uses standard front-facing connectors or back-connect ports to take full advantage of the internal cutout layout.
• Confirm the exterior wood finish selection if you prefer dark walnut over light beech accents.
• Review the included mounting accessories and hardware pack to verify what screws or brackets arrive in the box.

How to compare your options: When evaluating mid-tower enclosures, focus primarily on included cooling components, power supply clearances, and chassis cable management capabilities. This model differentiates itself by providing five factory-installed PWM fans, support for back-connect mainboards, and alternative power supply orientations, reducing the need for aftermarket cooling additions.

• Choose between the default balanced intake setting and the raised CPU mode depending on whether your graphics card or processor runs hotter during typical sessions.
• Evaluate your power supply cable length and plug positions before fastening the unit, testing both the standard and rotated mounting orientations to find the cleanest path.
• Take advantage of the back-connect motherboard support if your hardware supports rear cabling, routing main wiring harness bundles behind the tray to maintain an unobstructed interior airflow path.
• If you place the case in a low-clearance cubby or alternate side of your workspace, select the closer of the two power buttons for day-to-day access.
• Periodically clean dust buildup from fan blades and intake areas according to the manufacturer guidance to maintain quiet operation and steady cooling performance.

How many fans come installed in the case?
The case includes five pre-installed PWM fans right out of the box. These consist of two 170x30mm front intake fans, two 120mm reversed-blade fans, and one 140mm exhaust fan at the rear.

What is CPU mode on the front fans?
CPU mode is an adjustable configuration where both 170mm front intake fans are raised higher along the front panel. This position directs incoming airflow specifically toward your CPU cooler for focused cooling efficiency.

Does this enclosure work with back-connect motherboards?
Yes, the internal chassis design supports back-connect motherboards. This allows you to plug cables directly into the rear of the motherboard tray, hiding wiring from the main chamber and improving interior airflow.

What size power supply will fit inside?
The case accommodates power supplies up to 220mm in length. You can also choose between installing the power supply facing front or rotating it to optimize internal cable routing.

Why are there two power buttons?
The dual power buttons are designed for placement flexibility. Having two separate switches ensures you have easy physical access to power your PC whether the chassis sits on your desk, under a workstation, or on the floor.
