ArsenalPC Gigabyte C301 GLASS Gaming Desktop

This system pairs an Intel Core Ultra 9 285K 24-core processor running at 5.7GHz with an NVIDIA GeForce RTX 5070 graphics card carrying 12GB of GDDR7 memory. It includes 128GB of DDR5 RAM and a 4TB NVMe SSD, all powered by an 850W supply and cooled by a 240mm liquid cooler inside the Gigabyte C301 GLASS chassis with WiFi and RGB lighting. Windows 11 Home is pre-installed.

Suited for high-refresh 1440p gaming

The 24-core CPU and 128GB memory capacity handle streaming, content creation, and demanding applications alongside modern titles. Buyers who need more than 4TB of fast storage or who require a second graphics card for specialised compute tasks should consider a different platform.

4TB NVMe SSD primary storage

The single 4TB NVMe drive holds the operating system, games, and working files without additional drives included. If your library or project archive exceeds this capacity, you will need to add storage after purchase.

Questions about this item

How loud or hot does the 240mm liquid cooler keep the Intel Core Ultra 9 285K running at 5.7GHz all day?

The 240mm liquid cooler is designed to handle the 24-core processor at its 5.7GHz base frequency, keeping temperatures and noise controlled during extended gaming sessions.

Does the Gigabyte C301 GLASS case include the WiFi antenna and RGB controller so the system works out of the box?

Yes, the desktop ships tested and ready to play with WiFi and RGB lighting already integrated; no extra antennas or controllers are needed.

Will my older PCI Express x16 graphics card fit alongside the installed RTX 5070 if I keep it as a spare?

The motherboard provides a single PCI Express x16 slot occupied by the RTX 5070, so an additional legacy graphics card cannot be installed simultaneously.
