A:AnswerThe PC has a single DVI-D port that is not on the GTX-1070 card. The GTX-1070 card has 1 HDMI port and 3 display ports. I have included a photo for reference, hope this helps.
A:AnswerYes this machine comes with only one HDMI Port. This machine comes with an HDMI cord to plug into a monitor. So if you needed this HDMI port for any other device I would recommend purchasing a Display Port Cord for your monitor to free up this HDMI port.
This machine also has the capability and capacity to input additional HDMI ports on the back side.
A:AnswerNot sure if this is the case for all of these models to be sold by Best Buy or if I got really lucky, but when I received mine I found that the CPU is liquid cooled. A nice surprise, but like I said, it may have been accidental.
A:AnswerIt comes with a basic alienware keyboard and alienware mouse. Don't know that it lights up, if it does the alienware icon might, but probably not the keys, it is a basic end model of keyboard, no real bells or whistles. the mouse is a simple two button, no side buttons. wasn't expecting the mouse because the page didn't say it included one. just checked, the keyboard comes with multimedia buttons, but does not appear to light up when I plugged it in real quick. I included pics. It's a nice looking keyboard, but not fancy. upgrades are always your choice, based on what you're looking for.
