New to BI, and to the site. I've read the post that is referenced for what specs to look for in a BI computer, but I'm having a hard time finding anything remotely close to the prices listed in several of the posts when I do a search. For example, I've been searching eBay today, and the cheapest refurbished i5 or i7 6th gen that I can find is $500, with most over $600. I was able to find some 3rd generation workstations for around $350, but I thought I must be looking in the wrong spots or using the wrong search terms since some folks on here seem to be finding deals for $200-300. Any advice on sites or links to recent deals you found? By the way, if older generations are fine, I'm open to them too, I was just trying to follow the recommended specs. I'll not have a large system ( 4 x 2mp and 2 x 4mp all Dahua). I currently have them all run back to and powered from a Netgear 8 Port Gigabit PoE Smart Switch. I just need to add in the BI machine, and didn't want to buy something inadequate just to save a few bucks. Thanks for the help in advance.
