For sale on my local CL...see below for details.  I don't care at all about the GPU or the 320GB HD so ignore them.  I would add 4x 5TB HDs and the system would be used only for storage and Docker containers (maybe an occasional headless VM if I need to do something in Linux).

 

How are the specs?

 

Intel® Core i5-760 Processor 2.8 GHz with Zalman cooler
ADATA Premier Series AD3U1333C4G9-SH 4GBx4=16gb
EVGA NVIDIA GeForce GTX 460 1GB GDDR5 
GIGABYTE GA-P55M-UD2 LGA 1156 Intel P55 Micro ATX Intel Motherboard
Enermax iVektor ECA3310A-B Case
320gb Hard Drive
Thermaltake TR2-500 WATT Power Supply

 

 

Its old tech, 6-7yrs old, oddball socket 1156 so CPU upgrades are limited. CPU does not support VT-D so not great for VM's but it does support virtualization.

 

The board has 7 SATA ports so not bad but I am not sure if the onboard network adapter is supported under unRAID you might want to check it out, its the  RTL8111D 

 

If the person is asking more than $100 for the system I wouldn't touch it, just my two cents.
