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

Thermals are the Lian Li Lancool 207's selling point, particularly around the GPU, which makes it a solid pick for gamers. Reviewers credited the sturdy construction and the innovative fan placement that aims airflow straight at the graphics card. Building in it is less pleasant: cable management is poor and the PSU doesn't fit cleanly, which hurts usability. Gamers who want strong cooling without spending much will be pleased with the performance, but anyone who values an easy build should consider alternatives.

Strengths
  • — Excellent thermal performance, particularly for GPU cooling
  • — Sturdy build quality with reinforced panels
  • — PSU positioned at front to accommodate 2 shroud-top fans
Watch-outs
  • — Challenging cable management
  • — Power supply fit issues and complications
  • — Right side panel closing can be difficult with thick cables
