2026 verdict
Geekom GT1 Mega Ultra 5 is far the more powerful machine, built on an Intel Core Ultra 5 125H with Arc graphics and an AI Boost NPU, 32GB of DDR5 at 5600 MT/s expandable to 64GB, a 1TB PCIe Gen4 SSD, Wi-Fi 7, Bluetooth 5.4, two 2.5G Ethernet ports, two USB4 Type-C ports plus five USB 3.2 Type-A, an SD Card 4.0 reader, a Kensington slot, a VESA mount and HDMI cable in the box and a 3 year warranty, running Windows 11 Pro in a 680 g aluminium body. Asus Chromebox 5a (Celeron 4GB + 128GB) plays a narrower game at a much lower price: ChromeOS with automatic updates and Google admin console management, a Celeron 7305, 4GB of single-channel DDR4 and a 128GB drive, with seven USB ports, dual HDMI 2.1, DisplayPort 1.4, a micro SD reader and Wi-Fi 6E. Buy Asus Chromebox 5a (Celeron 4GB + 128GB) for managed browser-based deployments where simplicity is the feature; buy Geekom GT1 Mega Ultra 5 for a genuinely fast, modern desktop.

Frequently Asked Questions
Which is better overall, the Geekom GT1 Mega Ultra 5 or the Asus Chromebox 5a (Celeron 4GB + 128GB)?
Geekom GT1 Mega Ultra 5, with a Core Ultra 5 125H, 32GB of DDR5-5600, a 1TB Gen4 SSD, Wi-Fi 7, dual 2.5G Ethernet, two USB4 ports and a 3 year warranty. Asus Chromebox 5a (Celeron 4GB + 128GB) wins on price and ChromeOS management.
Which has the more modern connectivity?
Geekom GT1 Mega Ultra 5, with Wi-Fi 7, Bluetooth 5.4, two 2.5G Ethernet ports and two USB4 Type-C ports. Asus Chromebox 5a (Celeron 4GB + 128GB) offers Wi-Fi 6E and Bluetooth 5.4, but Gigabit Ethernet and no USB4 or Thunderbolt.
How much memory can each take?
Geekom GT1 Mega Ultra 5 ships with 32GB of dual-channel DDR5-5600 and accepts up to 64GB. Asus Chromebox 5a (Celeron 4GB + 128GB) ships with 4GB of single-channel DDR4-3200 and tops out at 16GB, which is the sharpest difference between them.
Are either of them good for gaming?
No. Geekom GT1 Mega Ultra 5 uses integrated Intel Arc graphics that owners describe as weak for games despite the marketing, and Asus Chromebox 5a (Celeron 4GB + 128GB) pairs Intel UHD graphics with ChromeOS, so it is further from gaming still.
Who should buy the Asus Chromebox 5a (Celeron 4GB + 128GB)?
Organisations rolling out ChromeOS for classrooms, reception desks or digital signage, who value automatic updates, central management, seven USB ports and four display outputs at a low price. For everyday performance and modern I/O, Geekom GT1 Mega Ultra 5 is the better machine.
