OMEGA SX-C3145A Case

OMEGA SX-C3145A is a middle tower case in classic black color, aimed at budget and semi-budget builds. It supports ATX, Micro ATX, and Mini ITX motherboards, giving you freedom in choosing the platform. The acrylic window on the side panel allows you to see the hardware, even though there is no RGB by default. The lack of included fans and power supply is a plus if you want to choose the cooling and PSU according to your needs and budget.

What you get

The case accepts graphics cards up to 250 mm, making it suitable for shorter and mid-range GPU solutions – a good option for eSports titles, office, or multimedia PCs. The maximum height for a CPU air cooler is 150 mm, so it is oriented towards shorter towers or stock coolers, without huge tower monsters. You can mount one 120 mm fan at the front to intake fresh air, and there is space for a power supply up to 170 mm, which is more than enough for most PSU models. The I/O ports on the front panel – 1 x USB 3.0, 1 x USB 2.0, and HD Audio – cover the basic everyday needs for flash drives, peripherals, and headphones.

• Case form factor Middle Tower, providing a balance between size, airflow, and ease of assembly.
• Support for ATX, Micro ATX, and Mini ITX motherboards, opening options from compact to standard gaming configurations.
• Maximum graphics card length 250 mm, suitable for shorter GPUs of low and mid-range.
• Support for CPU cooler up to 150 mm height – perfectly fine for more compact towers and stock coolers.
• Ability to mount 1 x 120 mm fan at the front panel for basic airflow intake.
• Top placement of the power supply with a length of up to 170 mm, convenient for standard ATX PSUs without unnecessary cable chaos.
• Front I/O with 1 x USB 3.0, 1 x USB 2.0, and HD Audio for easy access to ports and audio.
• Side panel with acrylic window, allowing you to see the components, although the case lacks RGB effects.

Who it is suitable for

OMEGA SX-C3145A is a good choice for a budget or office build, basic gaming configuration with a shorter GPU and standard air cooler. It is suitable if you want a compact middle tower case without water cooling and without unnecessary extras, but with a window and basic front ports. If you are aiming for a powerful high-end build with a long graphics card, massive air cooler, or serious water cooling, you will likely find it cramped here.

The most sensible aspect of this case is the combination of support for ATX motherboards, acrylic window, and reasonable limits for cooling and GPU length – enough for a practical, inexpensive, and tidy build without unnecessary frills.
