New to PC cases? What they are and what to look for

The case is the box that holds a desktop PC's parts, keeps them cool with fans and airflow, and sets how big and loud the finished PC is.

Do you need a PC case? Every desktop build needs one. It's also the part people see, so looks matter more here than anywhere else.

What to look for

  • Room for your graphics card's length and your CPU cooler's height
  • A mesh front panel and included fans for cooler, quieter running
  • The motherboard size it takes, and whether it fits on or under your desk

The full review

Where it fits

The 4000D AIRFLOW is an ATX mid tower with a perforated steel front panel. It takes Mini-ITX, Micro-ATX, ATX and E-ATX motherboards, up to 305mm x 277mm. Corsair includes two 120mm AirGuide fans, one at the front and one at the rear. It suits a standard gaming or workstation build where cooling and cable routing matter more than extras.

Airflow and cooling7/10

The front is a perforated steel high airflow panel. Fan mounts cover three 120mm or two 140mm fans at the front, two 120mm or two 140mm fans in the top, and one 120mm fan at the rear. Radiator support runs from 120mm to 360mm, with 360mm at the front and 280mm in the roof.

PC Perspective measured CPU load temperatures of around 75 C with a Ryzen 9 3900X and a 240mm AIO on top. Its GPU temperatures were unaffected by the case. Bit-tech reports CPU and GPU results a tad better than its open test bench, but says the case lacks active exhaust airflow. Owners praise the airflow and cool running.

Only two fans come in the box, and the mounts allow several more. Builders chasing lower temperatures have room to add fans or a larger radiator.

Space and compatibility7/10

The case takes graphics cards up to 360mm long and CPU coolers up to 170mm tall. ATX power supplies fit up to 220mm in length. With those limits, it has room for a long graphics card or a tower cooler, provided each stays inside the figures.

For storage, there is a combo 3.5in and 2.5in drive cage with two removable trays, plus two further 2.5in mounts. Owners describe the interior as roomy.

The front I/O is the weak point. Owners complain that there is only a single USB-A port on the front panel, which matters if you connect several peripherals or drives regularly.

Building in it7/10

Corsair includes RapidRoute cable management. Owners praise the roomy interior and easy cable routing, which points to a straightforward build.

The side panels are tempered glass. They come off with a thumbscrew rather than a tool-free latch. Some owners say the panels take force to remove, so expect to be careful with them when you open the case for upgrades.

Noise5/10

PC Perspective measured 34.1 dBA at idle and 38.4 dBA under simulated gaming load, with the meter 12 inches from the front of the case. KitGuru reports that the included fans are 3-pin, not PWM. Some owners complain about 3-pin fans and noise under heavy load.

Based on those reports, buyers who plan sustained heavy loads and care about noise should weigh this before buying.

Value7/10

Owners praise the value alongside the roomy interior. The case includes two fans, a high airflow front panel, RapidRoute cable management and support for E-ATX boards and 360mm radiators. The trade-offs are the single USB-A port, 3-pin fans and stiff side panels.

Who it suits

This case suits someone building a standard ATX or Micro-ATX system who wants good airflow and easy cable routing. It also gives room to grow into more fans or a 360mm radiator. It is a weaker fit for quiet-first builds or for anyone who needs several front USB ports.

What owners report

Recurring themes from public owner feedback, summarised in our own words.

  • Owners praise the airflow and cool running temperatures.
  • Owners like the roomy interior, easy cable routing and the value.
  • Some owners complain about the 3-pin fans and noise under heavy load.
  • Some owners dislike the single front USB-A port and the force needed to remove the side panels.
Who should skip it
  • Builders who want a quiet system under heavy load without swapping fans
  • Anyone who needs several front USB ports
  • Buyers who want tool-free side panels that come off easily
