256GB Plotting Workstations FS [Denver CO]

Hello, I have 2 plotting workstations that have served me well over the past 6 months (plotted over 2PB), but I no longer need this much plotting capacity, so I’m offering them up for sale here.
Hoping to find someone nearby (Denver, CO area) for an in-person transaction. Otherwise, will consider shipping to lower-48 US (buyer to pay actual shipping cost).
Bring your own GPU and SSDs. I recommend enterprise SSDs (e.g. Samsung PM983) for the plot destination/cache drive(s).
Prices are basically what I paid for the parts.

Lenovo P520 Workstation

256GB DDR4 2400 ECC (Micron)
2.72 minute bladebit C7 plot time (using RTX 3060 - not included)

Optional Extras (known to work well together)
10GB NIC Intel X520-DA1 (SFP+ connector) - $50
Dual M.2 PCIe 3.0 x8 adapter Supermicro - $40
Asus Hyper M.2 x16 v2 (PCIe 3.0 x16 to 4 M.2 adapter) - $70

No interest, so withdrawing ad for now. Looking into providing cloud plotting service via Akash (I know, the bottom fell out of that market). Just want the hardware to get some use before it’s obsolete.
