NVIDIA DGX Spark Founders Edition with 128GB unified memory and a 4TB NVMe SSD (NVIDIA part number 940-54242-0000). Four identical units available from my 4-node home lab cluster.

BUY 2, GET A MATCHED PAIR WITH THE CABLE

• Buy 2 and you get a matched pair that ran together in my cluster, plus the QSFP stacking cable that connects them.
• Ready to link over the built-in ConnectX-7 200 Gbps ports as a 2-node 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.
