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 #4 in Best Mid Tower PC Cases
Phanteks Eclipse G370A
3 sourcesall derived$56.98as of Aug 3

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
  • — No vertical GPU support
  • — 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 4000D RS no-RGB's modular design and 3D Y-pattern front panel outperform the Lian Li Lancool 207's basic airflow setup, though it lacks the Lian Li's GPU-focused fan placement. Unlike the Phanteks Evolv X2 Matrix, it doesn't include lighting but offers replaceable components and dual 360mm radiator support. Compared to the Thermaltake The Tower 250, it provides better internal space management and easier component access.

Phanteks Eclipse G370A

The Phanteks G70A provides high airflow and EATX support, which the Thermaltake The Tower 250 lacks due to its mini tower classification. While it doesn't include pre-installed fans like the Evolv X2 Matrix, it offers more robust cooling support for workstation builds. Compared to the Corsair 4000D RS no-RGB, it has fewer modular features but better support for high-end motherboards and AIO radiators.
