Question 1

Does this machine have an available pci express x16 slot? Looking to install a low profile HD5450 I have laying around for use as an HTPC. The machine would be running OpenELEC.

Accepted Answer

Hi Jesse, per the HP HW Reference Guide for the DC5700 on p20, there is a PCIE-x1 slot but no PCIE-x16. From the HP Support Web page for the DC5700 it says: "PCIe X16 video cards are not supported on these machines"

Hope this is helpful. 
Best regards,

Question 2

Does this include a Win 7 Disk?

Accepted Answer

There is no widows disk included with this computer. Windows 7 is pre-installed without any bloatware and ready with out-of-box-expericene. There is a recovery partition included on the drive which can help fix many problems.

Question 3

I ordered a Hp DC5700 with 2 GBS of RAM Memory . Can this be expanded to 4GBS or more of RAM?

Accepted Answer

The manual for the DC5700 says:
"The memory sockets on the system board can be populated with up to four industry-standard DIMMs.
These memory sockets are populated with at least one preinstalled DIMM. To achieve the maximum
memory support, you can populate the system board with up to 4 GB of memory configured in a high performing dual channel mode."

In other words, the computer supports up to 4 GB RAM.  There are four slots for the ram and each slot can support 1 GB RAM.

I hope this helps

Question 4

Does the motherboard have any type of gpu expansion slot?

Accepted Answer

If this is a PCI-E x16 graphics card it will not work. The dc5700 only supports PCI graphics cards or in the slot that looks like a PCI-E x16 slot an HP SDVO ADD2 card.

Question 5

USB 3.0??

Accepted Answer

USB 2.0

Question 6

How well does Linux run on this?

Accepted Answer

Just fine.  I installed Fedora 20 with no issues.

Question 7

Which of these HP listed video is in this:
Integrated Intel Graphics Media Accelerator 3000
DVI ADD2 SDVO single head Graphics Adapter (SDVO connector) *
NVIDIA Quadro NVS 280 64-MB PCI dual head VGA**
NVIDIA Quadro NVS 55 64MB PCI low profile DVI w/TV-Out?

Accepted Answer

Integrated.
The others are cards thus not in this PC.  I have not seen HP integrate video other than the standard chipset which is listed as integrated.  Somewhat confusing I agree.

Question 8

Is this wireless compatible?

Accepted Answer

You would have to add a PCI wireless card to it.
