Read the memory spec before you judge the price. This has 768GB of DDR4-2933 ECC — and it's built from six 128GB LR-DIMMs, not a pile of little sticks. That matters two ways: 128GB modules are the expensive tier and have gotten dramatically more expensive with AI demand driving DRAM prices, and because only 6 of 12 slots are filled, you can go to 1.5TB without throwing away a single stick you already own. Go price PC4-23400 128GB LR-DIMMs on eBay and then come back to this listing.
Specs:
Mac Pro Rack, 2019 (4U rack chassis, not the tower — no feet, slides into a rack - rails included)
2.5 GHz 28-Core Intel Xeon W (W-3275M) — the top CPU option
768GB DDR4-2933 ECC LR-DIMM — 6 × 128GB modules, 6 slots still open
AMD Radeon Pro 580X 8GB MPX module
256GB Apple SSD (boot) + 2TB NVMe on a PCIe card (data)
Dual 10Gb Ethernet, Thunderbolt 3, 1400W power supply
macOS Tahoe 26.6.2, fully updated
Clean and well cared for, no issues. Non-smoking, climate-controlled environment.
Price: $5,000 cash. Reasonable offers considered. Selling complete — not parting out the memory.
Trade considered: new, unopened NVIDIA DGX Spark. Founders Edition
How this works: I'm in WI and will meet at the Micro Center in St. Louis Park (Hwy 100 & 36th). I'll bring power and a display — the Mac will be booted and running in front of you, and I'll open About This Mac so you can see all 768GB reported by the system. On a trade, we open the Spark box and power it up too. Bring the purchase receipt.
No shipping. No third parties. No "I'll send it first." In person, or no deal.
