Wow $15 for that CPU sounds great.
Wild that it was released in 2016 for almost $9,000
Yea, old server hardware can be super cheap! In my opinion though, the core counts are misleading. Those 24 cores are not compareable to the cores of today. Plus IPC+power usage are wildly different. YMMV on if those tradeoffs are worth it.
Until you see your electricity bill.
