PC case design enters a new phase at Computex
PC case design refers to the engineering and aesthetic choices that balance airflow, component compatibility, cable management, and visual appeal in modern computer chassis. At Computex, that balance looked very different on the show floor, as Lian Li and be quiet presented contrasting answers to the same question: how do you push PC cooling solutions forward without sacrificing style or build flexibility? Their new LANCOOL 4 chassis and Pure Base 803 case families signal a shift away from simple mesh-versus-glass debates toward hybrid ideas such as curved tempered glass with active intake cut-outs, modular storage bays, and workstation-ready airflow paths. Both lineups are still pre-launch, but early prototypes make one theme clear: case airflow optimization is no longer a niche enthusiast concern, it is the central design brief for mainstream mid-towers aimed at powerful gaming and creative rigs.
LANCOOL 4: panoramic glass meets practical airflow
Lian Li’s LANCOOL 4 chassis aims to be the rare panoramic tempered glass design that does not punish thermals. It uses a three-sided glass layout with front and side panels made entirely of tempered glass, yet integrates three front-mounted 140mm dual light-zone fans in cut-outs on a curved glass front, turning the usual solid sheet into an intake surface. According to Overclock3D, Lian Li has “redesigned it and improved it” since last Computex while keeping a planned USD 129.99 (approx. RM610) price target. A modular lower chamber lets builders hide HDD mounts for a cleaner look or free the space to fit an optional 8.8-inch LCD. Two bottom fan mounts deliver direct GPU airflow, while the rear-mounted PSU creates an almost floating motherboard tray—an engineering flourish that underlines how form and function are being treated as equal priorities.
Pure Base 803: one platform, three airflow personalities
be quiet’s Pure Base 803 case takes a different approach, using a single deep chassis that can be tuned for airflow, storage, or lighting-forward builds. All versions support liquid cooling radiators up to 420mm and ship with four 140mm fans, but their focus differs. The standard Pure Base 803 arrives in black with four Pure Wings 3 fans and strong airflow and expandability. The Pure Base 803 LX adds tempered glass and Light Wings LX A-RGB fans in black or white for more eye-catching PC case design. A workstation variant replaces the glass front with mesh, supports three 140mm front fans, up to 10 hard drives, and EEB/CEB motherboards. With room for up to 11 140mm fans including three on the floor, the platform is clearly built around case airflow optimization for high-power GPUs and storage-heavy systems.
Engineering details: PSU placement, back-connect, and modularity
Both series show how internal layouts are changing to support cleaner builds and stronger PC cooling solutions. Lian Li moves the PSU to the rear in an unconventional orientation, which visually clears the main chamber and helps the motherboard tray appear to float behind the LANCOOL 4’s glass. That space can be used for bottom-mounted fans, aimed straight at the graphics card. In contrast, be quiet mounts the PSU at the top of the Pure Base 803, hiding it behind a shroud that does not intrude far into the chamber thanks to the case’s depth. The chassis also supports back-connect motherboards from ASUS, MSI Project Zero, and Gigabyte Stealth, and adds a metal cable management sleeve for tidy routing. Prototype samples even feature movable front I/O that can be installed on the front or top panel to suit desk placement.
What these prototypes signal for future PC case design
Although both lineups are still pre-release, the direction for PC case design is clear. Lian Li is pushing glass-heavy aesthetics as far as they can go without compromising airflow, turning the LANCOOL 4 into a potential reference point for affordable panoramic builds that still feed GPUs with direct intake. be quiet is treating the Pure Base 803 case as a flexible platform instead of a single configuration, spanning mesh-front workstations, high-storage servers, and A-RGB gaming towers from one shared frame. Across both, case airflow optimization, support for back-connect motherboards, and optional modules like LCDs or HDD cages suggest that future mid-towers will be defined less by fixed layouts and more by how well they adapt to different roles—from compact showcase rigs to deep, air-hungry workhorses.
