2 sources$99.99as of Oct 29

The Corsair Frame 4000D RS ARGB is a clear step up from Corsair's recent cases, built around a modular design that lets you swap parts for 3D-printed alternatives. Reviewers liked the airflow from the 3D Y-pattern front panel and the support for dual 360mm radiators. Construction is high-quality steel and tempered glass, and a rotatable GPU mount allows vertical GPU installation. The GPU bracket isn't as flexible as it could be, and the top panel doesn't come off, which complicates radiator installation. Budget-conscious builders after a well-designed modular mid-tower are the target.

Strengths
  • — Modular design with replaceable motherboard tray and power supply shroud
  • — Improved airflow with 3D Y-pattern front panel claiming 12% more airflow
  • — Supports dual 360mm radiators
Watch-outs
  • — GPU bracket lacks horizontal movement for flexibility
  • — Top panel is not removable for easier radiator installation

Phanteks Eclipse G370A
Ranked #5 in Best Mid Tower PC Cases
Phanteks Eclipse G370A
1 sourceall derived$58as of Oct 28

The Phanteks Eclipse G370A is a plain mid-tower aimed at high-performance builds, with a mesh front panel and room for SSI-EEB and EATX motherboards. Reviewers rated its cooling well, helped by pre-installed D-RGB fans and dedicated space for a 360mm radiator. There's no vertical GPU support and internal storage options are limited. Power users and professionals who want reliable airflow and nothing extra will be satisfied; budget-conscious builders aren't the audience.

Strengths
  • — High airflow design with support for up to 7x 120mm fans
  • — Supports SSI-EEB and EATX motherboards for workstation-grade builds
  • — Pre-installed 3x Phanteks M25 D-RGB 120mm front fans
Watch-outs
  • — Limited internal storage options with only 2x 2.5" SSD and 1x 3.5" HDD

How they stack up

Corsair Frame 4000D RS ARGB

The Corsair Frame 4000D RS ARGB has a modular design with a replaceable motherboard tray and power supply shroud, and it includes three 120mm fans where the Phanteks Evolv X2 Matrix ships with none. It supports dual 360mm radiators and up to ten 120mm fans, against seven on the Lian Li Lancool 207 and the Evolv X2 Matrix. Its top panel is not removable, which complicates radiator installation.

Phanteks Eclipse G370A

The Phanteks Eclipse G370A ships with three pre-installed 120mm D-RGB front fans, where the Phanteks Evolv X2 Matrix includes none. It supports SSI-EEB and EATX motherboards and, like the Lian Li Lancool 207, takes radiators up to 360mm. It has no vertical GPU support, which the Corsair Frame 4000D RS ARGB offers through a rotatable GPU mount, and it costs less than all three.
