This article covers RUIX CV303 コンピューターケース(ホワイト).

Overview

The RUIX CV303 is a mid-tower PC case that offers a tempered glass side panel at an affordable price point. Its white chassis gives a clean, modern look that brightens up any desk setup. Measuring 279mm wide, 424mm deep, and 414mm tall, it weighs 8.2kg — typical for a mid-tower enclosure. The case supports both air and liquid cooling, giving builders flexibility in their cooling choices.
This case targets a wide audience, from first-time PC builders to budget-conscious gamers. It comes with pre-installed fans, so you can start using it right away without additional purchases. The tempered glass panel lets you show off your components, making it a great choice for those who want to feature RGB lighting or a custom water loop.
In terms of market positioning, the CV303 sits comfortably in the entry-level to mid-range segment. While it may lack some premium features like advanced cable management or high-end materials, it delivers solid functionality at a very competitive price.

Compatibility Guide

The RUIX CV303 is a mid-tower case, so it should accommodate standard ATX, Micro-ATX, and Mini-ITX motherboards (though official confirmation is not provided). It accepts ATX power supplies, and a 650W PSU is a reasonable recommendation for most builds.
Storage drive support is likely present for 2.5-inch SSDs and 3.5-inch HDDs, but exact bay counts are not specified. Before purchasing, measure your intended motherboard, PSU, and storage devices to ensure they fit inside.
Crucially, the maximum GPU length and CPU cooler height are not officially stated. If you plan to install a large graphics card or a tall tower cooler, you must measure carefully or check user reviews for real-world clearance data.

Product Info

The RUIX CV303 was released around 2024 and is primarily sold through online retailers like online retailers. The price is approximately ¥38,506 (tax included). It is available only in white, with a construction of tempered glass and steel.
Cooling support includes both air and liquid cooling. Pre-installed fans are included, so you don't need to buy extra fans immediately. Warranty details are not clearly stated by the manufacturer, but standard return policies apply through the retailer.
Market positioning: entry-level to mid-range. The key selling point is the tempered glass side panel at a low price, making it ideal for budget-oriented builders.

Best Use Cases

  • First-time PC builders: The included fans reduce the number of components to buy, simplifying the build process. The glass panel lets you admire your work once finished.
  • Budget gamers: This case offers enough space for a gaming rig without breaking the bank. You can allocate more of your budget to the CPU or GPU.
  • White-themed builds: The white exterior pairs beautifully with white components and RGB lighting, creating a cohesive aesthetic.
  • Future liquid cooling upgrades: Since the case supports water cooling, you can add an AIO cooler later without replacing the case.
    Who should avoid this case?
  • Users planning to install oversized GPUs (over 350mm) or very tall CPU coolers (over 170mm) — clearance is unverified.
  • Those seeking premium build quality, sound dampening, or extensive cable management features — this is a budget case.

Things to Consider

The biggest caveat is the lack of official specifications for GPU length and CPU cooler height. If you're using large components, you'll need to measure yourself or rely on community feedback. Additionally, the specs of the included fans (size, noise level, airflow) are not disclosed, so if silence is a priority, consider replacing them.
Front I/O port details (USB type and count) are also missing from the product page. Check the listing or reviews to confirm it has the ports you need.
Competitors in this price range include the Thermaltake Versa H18 and Cooler Master MasterBox Q300L. The CV303 stands out by including a tempered glass panel as standard, but it may lag behind in brand reputation and customer support.

FAQ

Q: Does this case fit an ATX motherboard?
A: As a mid-tower, it likely supports ATX, but official confirmation is lacking. Measure your motherboard (244mm x 305mm) against the case's interior tray space before buying.
Q: Where can I mount a liquid cooling radiator?
A: The case is described as water-cooling compatible, but specific radiator sizes (240mm, 360mm) and mounting locations are not specified. Front or top mounting is typical, but contact the manufacturer for exact details.
Q: What size are the pre-installed fans?
A: Fan size is not officially listed. Most mid-tower cases use 120mm fans, so that's a reasonable guess. If you plan to replace them, measure after receiving the case.
