NVIDIA DGX Spark Founders Edition with 128GB unified memory and a 4TB NVMe SSD. Two identical units available from my home lab cluster.

BUY BOTH, GET THE STACKING CABLE

• Buy both units and you also get a QSFP stacking cable to connect them.
• Link them over the built-in ConnectX-7 200 Gbps ports as a 2-node setup.
• Only one cable is available, so it goes with a purchase of both new in spring 2026 and used in my home lab cluster for local AI model serving.
• I ran them power-limited the whole time they were in service, so they have seen less heat and stress than units run at full power.
• Fully working. Each unit is tested before it ships.
• The SSD is securely wiped and NVIDIA DGX OS is restored to the factory image before shipping. No accounts or data carry over.
• No dents or scratches.
