Questions about this item

What components come inside the Gigabyte C301 GLASS case and do I need to buy anything else?

The system ships with an Intel Core Ultra 9 285K 24-core CPU, 128GB DDR5 RAM, 4TB NVMe SSD, GeForce RTX 5090 32GB GDDR7 graphics, 240mm liquid cooler, 1200W power supply and Windows 11 Home pre-installed; no extra parts are required to start gaming.

Should I choose the 128GB DDR5 configuration or a smaller kit?

The 128GB DDR5 kit fills all four slots at DDR5 speed and matches the 24-core Ultra 9 285K for heavy multitasking and content creation; a smaller kit would leave slots open but reduce total capacity.

What does the 5.7GHz CPU base frequency mean for real-world frame rates?

The 5.7GHz base clock on the 24-core Ultra 9 285K keeps single-threaded game logic running fast, so the RTX 5090 32GB GDDR7 stays fed and high-refresh 4K gaming remains smooth.
