Overview

The MSI MPG GUNGNIR 300R Airflow White is a mid-tower PC case built for maximum airflow. Its full-length mesh front and top panels ensure efficient cooling, while the white finish and tempered glass side panel give it a clean, premium look. This case is ideal for gamers and enthusiasts who want to build a high-performance system without sacrificing cooling or aesthetics.
Out of the box, the case comes with four 120mm ARGB PWM fans (three front intake, one rear exhaust) and a six-port fan hub, so you can get started immediately. The included Mystic Light controller lets you sync lighting with other MSI components. The case supports E-ATX, ATX, Micro-ATX, and Mini-ITX motherboards, making it compatible with a wide range of builds.
Dimensions are 505mm (H) x 235mm (W) x 510mm (D), and it weighs about 10.2kg. The side panel is 4mm tempered glass, slightly offset from the chassis to improve airflow.

Compatibility Guide

Motherboard support: E-ATX (up to 305mm x 277mm), ATX, Micro-ATX, Mini-ITX. The power supply is bottom-mounted and can accommodate units up to 220mm in length.
Graphics card clearance: up to 360mm. The included adjustable GPU support stand helps prevent sag. CPU cooler clearance: up to 175mm, so most large air coolers and AIO pump heads will fit.
Storage: up to 2x 3.5-inch HDDs (slide-out cage) and 2x 2.5-inch SSDs (vertical dock). The front I/O panel includes USB 3.2 Gen 2x2 Type-C (20 Gbps), two USB 3.2 Gen 1 Type-A (5 Gbps) ports, and audio jacks.

Product Info

Released in late 2023, the MSI MPG GUNGNIR 300R Airflow White is positioned as a mid-to-high-end gaming case. It offers a strong balance of cooling, aesthetics, and features at a competitive price point. The warranty is typically 2 years (check regional terms).
The case is available in white only. It supports both air and liquid cooling: front and top can fit up to 360mm radiators. The rear supports a 120mm fan/radiator. There is also a side bracket for optional 60mm fan for M.2 SSD cooling (not included).

Best Use Cases

  1. High-end gaming PC builders: The excellent airflow keeps powerful components like an RTX 4080 Super and Core i9-13900K cool under load. The included fans and hub reduce initial costs.
  2. First-time PC builders: The case is easy to build in, with hidden cable channels, a slide-out HDD cage, and clear instructions. The price is reasonable for the feature set.
  3. White-themed PC enthusiasts: The all-white design pairs beautifully with white motherboards, GPUs, and memory. The tempered glass side panel shows off the build.
  4. Creative professionals (3D rendering, video editing): Long rendering sessions require stable cooling. This case’s airflow ensures sustained performance without thermal throttling.

Things to Consider

E-ATX support is limited to boards up to 277mm width. Extra-wide E-ATX boards (330mm) will not fit, so measure your motherboard before buying.
The tempered glass side panel is heavy and requires careful handling. Also, the offset design may allow more dust ingress, but included dust filters on front, top, side, and bottom help mitigate this.
The included 120mm fans are decent but not the quietest or most powerful. If you need extreme cooling or near-silent operation, consider replacing them with higher-end fans.
Vertical GPU mounting requires a separately purchased riser cable and fan. The bracket is included but the accessories are not.

FAQ

Q: Can I install a 360mm radiator in the top?
A: Yes, the top supports up to 360mm radiators. However, check clearance with tall RAM modules and VRM heatsinks; some thick radiators may interfere with the motherboard tray.
Q: How many fans can I install total?
A: The case supports up to 10 fans: 3 front (120mm), 3 top (120mm), 1 rear (120mm), and up to 3 on the side bracket (120mm). The included fan hub handles up to 6 fans.
Q: Is the PSU shroud removable?
A: No, the PSU shroud is fixed. But it has a large opening for cable routing, and the slide-out HDD cage is located next to the PSU area, making cable management straightforward.
