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.
