not all motherboards are the same size. see the form factor section in this
If you have a desktop style of computer it is likely that your motherboard will be one the few sizes available. Most full sized cases will accept smaller motherboards. see this rticle for a full description It begins "ATX (Advanced Technology eXtended) is a motherboard form factor..." see especially the box immediately to the right, the introduction, and the section titled "variants". If your upgraded mother board is the same size as your old one, it will fit. Check with either the manufacturers or your suppliers one the size f the motherboard, and the second article will give an idea of whether it will fit in your case (I didn't check the link 'motherboard form factors'). For example my case will hold a microATX board, 244mm or 9.6 inches square with little room to spare, I cannot fit a standard ATX m/b in there, but I should be able to fit a FlexATX or a mini-ATX [150mm square] in there.

I'd advise to check everything before make any purchases.

I have an Hp m260n. I just need to find out what type of case it has (ATX or uATX).

Motherboard: ASUS P4SD Motherboard Specifications

Board Form Factor: uATX

uATX stands for Micro-ATX,

HOWEVER, the Power Supply is an ATX form factor,

,of a sort.

Form Factor related directly to desktop computer Motherboards.
Now has 'evolved' to relate to the computer case, and Power Supply.

When referring to a Power Supply, and the ATX form factor; you are not only referring to the size, and shape of the Power Supply's case; but also the type of power cables used, and the technology used within.

Size and shape of an ATX power supply is approximately;

6 Inches Wide, 5.5 Inches Long, and 3.5 Inches in Height.
(152.39mm Wide, 139.69mm Long, and 88.89mm in Height)

Power cables included with Power Supply's nowadays, will include all the power cables you'll need, with probably some left over.

HOWEVER, looking at the 'ATX' form factor designated for your computer, to wit from the ad above, it does NOT fit the above size, and shape.

More like 6 Inches Wide, 4 Inches Long, and 3.5 Inches in Height.
Looks like they just crammed everything into one small box.

Remove motherboard, and all internal hardware, into a new computer case?
No prob!

Most Mid-Tower to Full Tower size computer cases, will have a Support Plate that accommodates a Micro-ATX form factor motherboard, OR an ATX form factor motherboard.

Just look at the Support Plate mounting holes.
Ones for a Micro-ATX (uATX) motherboard, will have uATX next to them, or MATX, or mATX.

Ones for an ATX motherboard, will have ATX next to them.

However check the computer case manufacturer info to be sure.

[ The motherboard mounts to a Support Plate.
The Support Plate can be an integral part of the metal frame, of the computer case; or a separate metal plate that attaches to the computer case metal frame ]

Hi, I have a Hp Compaq dc 7600 small form factor pc with a hp09f8h motherboard. I was wondering what 4 channel sound cards would fit this machine. Thanks.

This PC should have a riser card inside it. You should be able to fit any PCI sound card in there.

Please remember to rate my solution to show your appreciation.

How to upgrade from usb1.1 to usb2.0?

You'll need to install a usb 2.0 card into the slot of the computer if one will fit your pci slot or pci express slot if the motherboard supports those form factors.

Then, you'll be able to connect usb 2.0 devices to the computer in the back.

Looking to build using hp 5716 case. need to know where to find out what mb will fit case.

The size of a motherboard, is the Motherboard Form Factor.

I'm willing to bet the Presario 5716 uses the Micro-ATX form factor, but could be wrong, and it could be the ATX form factor.

I base this belief on the factor, that I think the Presario 5716 uses a Mid Tower size of computer case.

The motherboard Micro-ATX form factor size, is 9.6 inches by 9.6 inches.
(9.6 inches is about 9 and 5/8th's inches.
5/8th's of an inch = .625)
Metric conversion for the above is 244mm by 244mm)

The ATX form factor size is 9.6 inches by 12 inches. (244mm by 305mm)

Inside the computer case is a Support Plate. The Support Plate, is what the motherboard screws down to.
Sometimes it's a separate piece, but for the Presario 5716 it's probably riveted to the case.

Looking at the Support Plate, you may notice the abbreviations mATX, and ATX by the motherboard mounting holes on the Support Plate.

mATX standing for Micro-ATX, and ATX standing for the ATX motherboard size.
This will be more readily spotted with the motherboard removed.

If so you can use either form factor of motherboard. You may Not be able to reuse the I/O plate, (I/O Shield), at the rear of the computer case. (Input/Output shield - plate)

The shiny rectangular, thin piece of metal, that covers the I/O ports. (Examples: Mouse, Keyboard, and Monitor to name a few I/O ports)

This rectangular plate pops out with a BIT of persuasion. The new motherboard should come with it's own matching I/O Shield.


The inside edges of the computer case, where the I/O Shield is mounted, are SHARP!! Use extreme caution, and perhaps gloves to remove the I/O Shield.

Once the old I/O Shield is removed, it is readily apparent of how to install the new one, and could avoid possible confusion of me trying to explain here.

Sometimes the I/O Shield that comes with the new motherboard is not a direct replacement, as to fitting in the existing rectangular hole, in the computer case.
In this instance, a little modification is in order to the computer case.
(IF so, remember to smooth the edges with a file)

This link to Wikipedia explains the motherboard form factor pretty well, and also has photos, and charts,

(You can click on any photo to enlarge it. There is a chart at the bottom of the page)

Now you know,

A) Motherboard Form Factor
You can measure the old motherboard for it's size, and know what form factor it is.

B) Support Plate, and the mATX, and ATX designations that may be stamped, or printed near the motherboard mounting holes, on the Support Plate.

If the old motherboard is not obtainable, you can look for the above designations, to see what motherboard form factors apply.

You can also use a tape measure, and measure the distance in-between the mounting holes, and obtain a rough guess.
It won't be that rough a guess, when differentiating between 9.6 inches, and 12 inches.

C) When looking at a website that sells motherboards, you can look in the specifications description, and look for the designation ATX, or MATX, to see if that particular motherboard will fit in your Presario 5716 computer case.

(mATX, and MATX = Micro-ATX)

As for buying a motherboard that will equal the specifications of your old motherboard, good luck.

You can buy an exceedingly cheap motherboard now, that will outperform your old one, like a dragster flying by a snail, in comparison.

You won't be able to reuse the old Processor, and is doubtful that you can reuse the Ram Memory.

The Ram Memory, is SDR Sdram, that operates at a frequency rate of 100MHz FSB. (PC100)

(Single Data Rate Sdram is commonly just referred to as Sdram. Speed is slang for Frequency Rate)

The Processor, is either an Intel Pentium III that fits in a Slot 1 processor socket, or the Pentium III type that fits in a Socket 370 processors socket.

The Pentium III processor, that fits in a Slot 1 processor socket, is about 5-1/4 inches long, and 3 inches tall. It should have a black plastic case around it. Thickness is around 3/4th's of an inch.

The Pentium III processor that fits in a Socket 370 processor socket, is about 1-1/2 inches by 1-1/2 inches, and is square.

The Pentium III processor used in the Compaq Presario 5716 operates at a maximum frequency rate of 450MHz. (MegaHertz)

This gives you an indication, of what a Pentium III Slot 1 processor looks like,

What form factor is the motherboard

The form factor of a motherboard determines the specifications for its general shape and size. It also specifies what type of case and power supply will be supported, the placement of mounting holes, and the physical layout and organization of the board
