The adoption of NVIDIA’s GB10 Superchip continues to expand as more manufacturers enter the market with compact systems built around the platform. H3C is the latest company to join this lineup, introducing its new LinSeer MegaCube Mini PC in China. The system arrives as several major OEMs—such as Dell, Lenovo, HP, ASUS, MSI, Acer, and Gigabyte—have already launched their own GB10-powered compact Mini PCs priced between $2500 and $3500 US.
H3C’s entry goes in a different direction with a compact 150 x 150 mm chassis and a gold finish, positioning the MegaCube as a high-performance Mini PC aimed at users working with intensive computing and AI workloads.
Inside the Mini PC, the LinSeer MegaCube carries a 20-core ARM CPU layout, built around 10 Cortex-X925 performance cores and 10 Cortex-A725 efficiency cores. The GPU uses NVIDIA’s Blackwell architecture and includes 6144 CUDA cores, placing it among the more capable options available in this size class. H3C equips the system with 128 GB of unified LPDDR5X memory, which contributes to the device’s ability to handle larger datasets and memory-heavy AI tasks.
Storage options include support for up to 4 TB of NVMe capacity. Power consumption peaks at around 100W under full load, which is notable for a device of this size and category. The Mini PC ships with NVIDIA DGX OS pre-installed, and a recent OTA update from NVIDIA adds new optimizations and general improvements to the platform.
The MegaCube is targeted at users who require local hardware capable of processing large models. According to H3C, a single unit can run AI models of up to 200 billion parameters. For more demanding scenarios, the system can be scaled by stacking up to four units, enabling support for Qwen3-coder 480B (INT4), Llama 3.1 405B (FP8), and Qwen3 235B (FP8).
H3C recently showcased a setup with four MegaCube units operating together at a technology exhibition in China, demonstrating the platform’s ability to handle high-capacity AI workloads in a compact configuration.
The H3C LinSeer MegaCube is listed at 36,999 RMB on JD.com—equivalent to over $5000 US. This places it well above the pricing bracket of most other GB10-based Mini PCs, positioning it as a premium option. The higher cost can be attributed to the large 128 GB memory configuration, advanced hardware, and the increasing market demand for AI-focused systems.
As interest in AI hardware continues to grow, more manufacturers are expected to release their own GB10 solutions. For now, the H3C LinSeer MegaCube stands out as a compact Mini PC built for demanding tasks, offering a blend of size, performance, and scalability for professional workloads.
