ATX PC case Evolveo EVOLVEO T3 — mid-tower ATX chassis, standard form factor

Evolveo EVOLVEO T3 is a mid-tower ATX chassis designed to house standard ATX and Micro-ATX motherboards and conventional desktop components. The case places the power supply in the lower compartment, includes a front mesh with a removable dust filter and features a transparent side panel for internal visibility. Internal drive capacity supports a front external 5.25" bay, two internal 3.5" drive bays and three dedicated 2.5" SSD mounts (or up to five 2.5"/3.5" drives combined). Expansion support includes seven PCI slots and room for long graphics cards up to 400 mm. Factory-installed cooling comprises two 120 mm blue LED fans (one top, one rear); the front panel accepts two 120 mm or two 140 mm fans. Front I/O provides two USB 2.0 ports and one USB 3.0 port. The chassis dimensions are 455 x 205 x 482 mm.

Advantages

The Evolveo EVOLVEO T3 offers a conventional mid-tower layout with lower power supply placement, a dust-filtered front intake and a transparent side panel for component access and visibility. It supports a range of drive configurations and long graphics cards, while preinstalled LED fans and multiple fan mounting points enable basic airflow out of the box and room for additional cooling. Front USB 3.0 alongside USB 2.0 ports provides a mix of modern and legacy connectivity.

Suitable for

• Office desktop builds using ATX or Micro-ATX motherboards
• Home or casual gaming systems with a single long graphics card (up to 400 mm)

How to use

Install the motherboard on the included standoffs and secure it with screws, then mount the power supply in the lower compartment following the PSU orientation indicated by the chassis. Fit storage devices into the dedicated 3.5" and 2.5" bays or use the 5.25" bay for compatible optical or front-panel devices. Install the graphics card into the PCIe slot and secure it to the expansion bracket; verify that its length does not exceed the 400 mm clearance. Connect front I/O cables for USB ports and case fans to the motherboard headers, and route power and data cables neatly to maintain airflow. Use the transparent side panel to check component fit and cable routing before closing the case.

Usage recommendations

For reliable airflow, use the installed blue LED fans together with two additional front fans (120 mm or 140 mm) as intake. Clean the front dust filter regularly to maintain intake performance. When planning high-performance cooling or multi-GPU layouts, verify component heights and clearances against the 163 mm CPU cooler limit and the 400 mm GPU length limit.
