I am selling one of my harvester / slow plotter. It has being configured and running 24/7 for three months. Very stable. I am working on consolidating my hardware and making things more organized so I am selling some bigger machines.
The core of this harvester is a HP Z210. Spec list below
CPU = Xeon E3 1230 (4/8)
Memory = 16GB
Some kind good video card for Z210’s time. This Xeon CPU has no on board video so there must be a video card.
Motherboard has 6 SATA ports.
One two port PCI-e SATA card
Total 8 hard drives. One 250 GB for system. Three 3TB Hitachi. Two 4TB Hitachi. Two 6TB WD.
Total 29TB for Chia.
One air cooled 5 hard drive cage fit in the three 5.25 slot of the case. Case has three internal 3.5 slot. So eight hard drives is the most it can fit.
USB 3.0 PCI-e card two port. Z210 itself has no USB 3.0
With a Crucial P5 NVMe in one of the x4 slot, It can do one Mad Max plot (Windows 10) every 110-115 minutes. That is 12 plots a day.
It is running none stop in my chia farm. I hooked up as much as 13 external hard drive on it by USB. Also it does plotting none stop to feed hard drives. Hard drives in there are not new. They all running well.
I am selling this 29 TB rig (no NVMe SSD) for $800. I can fill this rig with your plot (total 260ish plots). It will takes me a week to finish.
I am in USA Philadelphia area.
