The Corsair Frame 4000D RS ARGB represents a significant improvement over Corsair's recent case offerings, featuring a modular design that allows users to replace components with 3D-printed alternatives. Reviewers praised its enhanced airflow with the 3D Y-pattern front panel and dual 360mm radiator support. The case is built with high-quality steel and tempered glass, and includes a rotatable GPU mount that supports vertical GPU installation. However, some reviewers noted limitations in GPU bracket flexibility and the non-removable top panel, which complicates radiator installation. This case targets budget-conscious builders seeking a well-designed, modular mid-tower chassis.

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 G70A
Ranked #4 in Best Mid Tower PC Cases
Phanteks G70A
$179.99as of Jul 1

The Phanteks Eclipse G370A is a no-frills mid-tower PC case designed for high-performance builds, featuring a mesh front panel and support for SSI-EEB and EATX motherboards. Reviewers noted its strong cooling performance with pre-installed D-RGB fans and dedicated 360mm radiator space. While it lacks vertical GPU support and has limited internal storage options, it's positioned as a solid choice for power users and professionals seeking reliable airflow without unnecessary features. It's best suited for those building high-end systems rather than budget-conscious builders.

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 4000D RS no-RGB

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 G70A

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.
