Hewwo! n.n I'm new to servers 'n stuff and I was looking at buying a refurbished HP z820 like in link provided: https://www.newegg.com/Product/Product.aspx?Item=9SIA5YV5S48689&cm_re=hp_z820-_-1VK-001E-0BMR6-_-Product
Does anyone have any knowledge about this?I've been looking around the 'net for reviews 'n stuff. I want to host a little minecraft server, ark, 7 days to die and other small things. Can this support 2 cpus and it just comes with one? Should I purchase some hyper 212 evos to cool it? Thanks for any help.
