Hp EliteDesk 800 or Dell optiplex 9020 tower

1. Hi guys. So far I found the two main recommendations for pc’s running blue iris are the HP eliteDesk 800 the optiplex 9020.
   
   I am looking at two systems for sale ex business owned models both for a reasonable amount around $450 to $550 there are a couple
   Out there. I would like to know if anyone has any pros and cons on either pc’s ? Also please correct me if I’m wrong but it appears the Optiplex has only one bay for the hdd. Will this be a issue?
   
   I want to run 6x 1080p cams at a reasonableviewing frame/second. Preferably I would like a
   Month of storage 2 cameras full time and the remaining on motion.
   
   Also on unrelated subject does anyone have any recommendations on dome PTZ cams would eventually like to implement one in

An i5 CPU should be able to run 6x 1080p cameras at whatever frame rates you want, as long as you've configured the system according to Optimizing Blue Iris's CPU Usage | IP Cam Talk

I suggest at least a 6 TB hard drive. Assuming you have the cameras encode at 6 Mbps each, it will take 4 TB to save 2 streams for 1 month. (12 Mbps * 1 month - Google Search) The remaining space can be used for motion recordings from the other cameras. You can set up two storage directories in Blue Iris both on the same hard drive but with different size limits. Set your two constant recording cameras to one storage directory, and set the remaining cameras to the other directory. This way your motion recordings have a dedicated amount of space and can last longer than a month.
