Question 1

video card?

Accepted Answer

We bought 5 of these for the office. They have onboard graphics only... no separate cards.  Onboard graphics are OK but we added very inexpensive ($23) cards with dual monitor support and it really perked up our CAD software.  No fancy 3D stuff, just basic 2D CAD.  GREAT deal on the PCs... $199 ea.

Question 2

Does this have HDMI Output?

Accepted Answer

No, it has VGA and Display Port output only.  I purchased an inexpensive video card from Newegg ($35) to add HDMI and DVI output for dual display.

Question 3

Does the OS come pre-installed and/or does it come with a W-7 pro 64 bit CD?

Also, does it have empty HDD slots for additional HDD's?

Accepted Answer

It has space for several other 3.5" hard drives and the install is tool free including the cover removal.
This is a very nicely designed case.

Question 4

is this upgradeable to a atx corsair cx500 power supply and EVGA Geforce GT740 graphics card?

Accepted Answer

I put an Nvidia GeForce GT420 Video card in mine.  The case is a full size  standard so I think it would pretty much accommodate any power supply or video card upgrade.

Excellent computer for the money

Question 5

Can you tell me the name of the mobo that is in this pc? One person answered that it did not have an ide connecter on the board. I need to know if that is true. Although a scsi hdd is known to be faster than ide, I prefer ide as some of my hardware is ide!!!
And I also ASK if it's possible to put a parallel port in a pci slot?
NEED to know before I buy! Thank You Beegee

Accepted Answer

As noted by others, no, there is no IDE port, but neither is there any SCSI- both are generally considered long outdated.  Instead, the unit I received has 4 of the more modern SATA ports inside, 2 of which are being used for the hard drive and optical drive.  1 PCIEXP X16 slot with a PCEEXP x4 right next to it and a PICEXP X1 just below that.  Of more interest to you, there are also 3 normal PCI slots.  It is possible to put a parallel port in a PCI slot, and Newegg probably has some of the cards to sell.  The pictures give a mostly accurate idea about the quantity and type of slots and expansion bays, but the computer I received has a significantly different internal layout.

Question 6

I am looking for an Upgrade for my computer, how well would this Comp run for games seems to have plenty of space but not to sure about the graphics card?

Accepted Answer

This PC has integrated graphics which will work for basic games, but not for any of the GPU intensive games and the power supply is not large enough to drive a high end video card.
This is an office/business PC and will browse, run office apps and other basic functions and will do it well.
It's used for that and as  a media server here in the house.

Question 7

Is it possible to add a parallel port to the io panel, do they make a an animal called a pci parallel port?

Accepted Answer

the mother board has a header for a parallel port.  You may get lucky and have a backplane adapter included, otherwise you will have to add one.  NewEgg does sell PCI and PCI express parallel port cards

Question 8

Does this PC have a RJ45 Lan Port, a parallel port, how many usb ports does it have & how many & what kind of PCI slots is on the motherboard? Is audio & graphics all on board? What is the max mem for upgrade? Does it have a 15 pin video display?
I can't view the back io panel from the picture shown, or I could look myself. Or provide the total specs. Thank You, Beegee

Accepted Answer

There is a specifications document on the HP web site under the C7900 model PC that should answer all your questions:

There are 6 rear and 2 front USB ports
One RJ45 rear
One VGA rear
4 DDR2 memory slots (all occupied with 1GB each)  16GB max
3 PCI slots
2 PCI2 x16
1 PCIe x1
Rear audio in and out
Front audio in out and mic in
Three full size bays intenal
One half bay internal

No IDE connector on motherboard

Question 9

would this be a good computer for at home use? for email shopping surfing the net and playing games..etc.

Accepted Answer

The system is pretty barebones, so it is a wonderfully inexpensive solution for those tasks.  High-end gaming may require ram and video card upgrades, but general online stuff should be fine.

Question 10

Does it have any antivirus software installed and what kind of network card/wireless adapter is onboard. does it have hdmi output?

Accepted Answer

No AV installed. RJ-45 on Motherboard. I'm not at the computer and I don't know the network speed.  Only VGA on motherboard.
