PC Case Thermaltake H550 TG ARGB Midi Tower Black, Grey

The Thermaltake H550 TG ARGB mid-tower chassis features a 2mm diamond-cut aluminum front panel with an integrated ARGB light strip and a preinstalled 120mm 5V ARGB fan at the rear. The case includes a 4mm tempered glass side panel, removable magnetic dust filters, a riser GPU support bracket and supports standard ATX, micro‑ATX and mini‑ITX motherboards. Dimensions are 225mm (W) x 441mm (D) x 472mm (H), and it is available in black and grey finishes.

Advantages

The H550 TG ARGB offers addressable RGB lighting controllable via motherboard RGB software or the RGB button on the top I/O, providing synchronized illumination. The 4mm tempered glass panel gives a larger, clearer view of internal components while improved dust filtration with magnetic top filters and bottom filters helps maintain component cleanliness. The included riser GPU support bracket and dual GPU placement option allow vertical GPU mounting and reduce card sag. One preinstalled 120mm ARGB fan with 9 addressable LEDs and hydraulic bearings supplies airflow and customizable lighting out of the box.

Suitable for

• Gaming PC builds with ATX, Micro‑ATX or Mini‑ITX motherboards
• RGB-focused systems that require motherboard software synchronization (5V addressable header)
• Users who want a tempered glass display window and good dust filtration
• Builders who plan vertical GPU mounting or need GPU support to prevent sag

How to use

Install your compatible ATX, Micro‑ATX or Mini‑ITX motherboard and mount drives in the provided 3.5" and 2.5" bays. Connect the 5V ARGB header from your motherboard to the case lighting or use the RGB button on the top I/O to cycle lighting modes. If you plan vertical GPU mounting, install the included riser GPU support bracket and, if required, a PCI‑E riser cable (sold separately). Fit fans and radiators as needed within the supported layouts and attach magnetic dust filters for maintenance access.

Recommendations

For full ARGB control use a motherboard with a 5V addressable RGB header and compatible software (ASUS Aura Sync, GIGABYTE RGB Fusion, MSI Mystic Light or ASRock Polychrome). Regularly remove and clean the magnetic top and bottom dust filters to preserve airflow and component longevity.
