Question 1

does it have a valid coa for windows 7 o/s?

Accepted Answer

I don't remember getting a certificate of authenticity with the computer. Win 7 comes loaded on the machine, not as a separate disc - you are allowed to make a backup copy.
But MS has accepted the software and is furnishing updates, so I presume if the Win 7 authentication is good enough for Bill Gates, it's good enough for me.

Question 2

does it have COM port? Thanks

Accepted Answer

no it does not. it has four USB ports on the back and 2 USB ports on the front all are high speed. There is a serial connection for a printer and a VGA monitor plug in and one other connection that I'm not sure what it is for.

I hope this helps.

Question 3

Does this come with a graphics card compatable  for a dual screen monitor?

Accepted Answer

The system only has one VGA port. It needs a separate video card (low-profile) that can support dual display.

Question 4

Is it wireless?

Accepted Answer

No, it is not wireless. It has a standard gigabit ethernet adapter built in. A wireless adapter would have to be added.

Question 5

DOES THE SYSTEM HAVE A NIC CARD INSTALLED?

Accepted Answer

It has a built in ethernet port, you can kind of see it in the picture of the rear of the tower.

If you want to have wireless with this tower, you'll need to buy a low profile pci wireless card or a wireless usb adapter.

Question 6

I am on dial up is this computer compatible?

Accepted Answer

Computer does have a 10 base 100 Ethernet port.  You would connect this port to your router and follow the instructions of your provider to set up your internet.

Question 7

Hi guys,
Recommend me low profile graphic card with HDMI for this computer? Thanks!

Accepted Answer

http://m.newegg.com/Product/index?itemnumber=14-102-882 Fro watching tv or video, which I am assuming is your purpose because this system has limited gaming ability because of processor bottleneck and you are requiring HDMI. But if you are wanting to game then go for http://m.newegg.com/Product/index?itemnumber=14-500-341

Question 9

Adding video card?

Accepted Answer

yes but you would need a low profile card (LP) its a slimmer shorter card and make sure its correct input as in (pci-e x16 etc.)

Question 10

Can the OS be transfered to another computer?

Accepted Answer

It is installed already, but comes with the 7 disk so you can use it on an other computer as long as you don't activate it on this one. I did that and used this one with an old XP disk that still had an activation left on it. The one I bought cost way less than Win 7 x64 by itself. The disk is only good for one install with activation. If you want to use the disk for another computer, Do Not Activate your new computer.
