This article covers Thermaltake Core P3 TG Pro オープンフレーム ATX PCケース.

Overview

Thermaltake's Core P3 TG Pro is an open-frame ATX mid-tower PC case that showcases internal components through a large tempered glass panel. This upgraded version of the popular Core P3 series adds a USB 3.2 Gen2 Type-C port, improved flat feet for better stability, and enhanced clearance for oversized hardware. Measuring 535 x 268 x 500 mm (with feet), it accommodates CPU coolers up to 180 mm tall, graphics cards up to 450 mm long, and power supplies up to 200 mm deep, making it one of the most spacious cases in its class. Designed for wall-mounting as well as traditional horizontal placement, the Core P3 TG Pro appeals to builders who want to turn their PC into a centerpiece. It occupies a mid-to-high-end market position, blending show-stopping aesthetics with generous expansion capabilities. The open frame with a glass shield offers an unobstructed view while protecting components from accidental contact.

Compatibility Guide

The case supports ATX, Micro-ATX, and Mini-ITX motherboards. Drive capacity includes up to four 3.5-inch and five 2.5-inch drives (both require optional brackets). Expansion slots total eight, allowing for multi-GPU setups or additional capture/network cards without crowding. Cooling compatibility is extensive: the motherboard side can house up to three 120/140mm fans or a radiator up to 420mm. The front/top area also supports three 120/140mm fans (with included bracket) or a 420mm radiator. No fans are included, so you must purchase cooling separately. The PSU mounts at the bottom and fits units up to 200 mm long. GPU clearance is a generous 450 mm (330 mm with a reservoir installed), and CPU cooler height maxes out at 180 mm. This ensures compatibility with flagship graphics cards and large air coolers or AIO pump blocks.

Product Info

Released in late 2022, the Core P3 TG Pro carries a three-year warranty via official Japanese distributors. Pricing typically ranges from ¥18,000 to ¥22,000, which is competitive for an open-frame case with this level of feature set. The case is positioned in the mid-to-high tier, appealing to enthusiasts who prioritize visual impact and flexible layout options. Its modular design allows for vertical, horizontal, or wall-mounted orientations.

Best Use Cases

  1. Custom water-cooling builders: With support for up to 420mm radiators, you can build elaborate custom loops with multiple radiators. The open layout provides ample space for pumps, reservoirs, and tubing runs. 2. PC showpieces: LED lighting, sleeved cables, and unique component designs are fully visible through the tempered glass panel. Wall-mount capability lets you integrate the PC into your room’s decor. 3. High-end hardware integrators: The extreme clearance for GPUs, coolers, and PSUs means no compromises when building with top-tier parts. Eight expansion slots allow for dual GPUs or multiple PCIe devices.

Things to Consider

The case ships without any pre-installed fans, so you'll need to budget for cooling components separately. Dust accumulation is a concern due to the open design, so frequent cleaning is recommended. The tempered glass panel, while durable, is still breakable if mishandled. Additionally, drive brackets are not included for 3.5-inch and 2.5-inch mounts, so plan ahead if using many drives. First-time builders may find the cable management and mounting process slightly more challenging than a traditional enclosed case, so reviewing the manual beforehand is advised.
