Question 1

the "display ports" it shows on the back is that HDMI?

Accepted Answer

No they are display ports.  Different format.  There may be a cable that has display port plug on 1 ent and hdmi on the other.  Or if you have DVI inputs on you monitor(s) like I do you will need cable with display port plug on 1 end and DVI on the other.

Question 2

Does this computer have the space and power supply to add an additional hard drive? I need more than 512GB.

Accepted Answer

Yes.  I had installed two additional drives as I need to do video work.  An extra 3.5" drive will fit below the original if you have the plastic sliders that are secured to that drive;  The other area is below the DVD drive.  However, it's made for 5.25" drive, so you might need to make adjustments and have the adapter hardware (for 3.5" drive) and cables.  I used the Sata ports for my drives.  FYI--be sure to inspect your delivery (mine was kind of kicked in the rear from shipping).

Question 3

Does this system have a built in WI-Fi?

Accepted Answer

Should probably contact the seller.  The one we bought does not, but since these are all used it would depend on how the individual unit was ordered.

Question 4

Would this pc be a ok gaming unit if i add a graphics card that i have already to it?

Accepted Answer

The Dell Optiplex 9020 Mini-Tower Desktop comes with a quad-core Intel Core i7-4770 processor, 16GB of DDR3 RAM, and a 512GB SSD. While it has integrated Intel HD Graphics 4600, you can add your own graphics card to enhance its gaming performance.

Question 5

does this unit have wifi?

Accepted Answer

The unit I received does NOT have integral WiFi. It does have an Ethernet jack which is what I use to connect it to our network.
