Re: Motherboard Issues.

I have just chosen the Gigabyte G31T-M Mobo for the replacement of a lesser quality one.

1) dual channel memory - supported by G31 chip set to DDR2 800
2) CPU upgradeability - FSB 1333 Mhz, Quad core
3) SATA 3.0 ( Raid optional ) - ICH7 std. or higher
4) Reasonable price - $80 usd

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 ]

What is the motherboard form factor of the Sony VAIO PCV-J120 PC Desktop motherboard?

Micro-ATX (mATX, or MATX)

To be sure there is a guide to use.

A full ATX form factor motherboard measures 12 inches by 9.6 inches. 305mm by 244mm
(9.6 inches is approximately 9 and 9/16ths inches)

A Micro-ATX form factor motherboard measures 9.6 inches by 9.6 inches. 244mm by 244mm

Need to know which style of m b I have is it an atx

The difference between ATX and MicroATX is the size. An ATX board will usually have 6-7 slots to add cards like video, network or sound cards. An ATX board will also usually not have a video port on the board. A MicroATX board will usually have only 3-4 slots to add cards into it, at least one of which being dedicated to AGP or PCI Express Video cards.
To answer your question: That computer uses a MicroATX board. A Micro ATX board will most likely work in any PC Case whereas an ATX board requires an ATX size case (Mid or Full size Tower).

I would like to move it in to a bigger case

When looking at the specifications of the HP Compaq DC7700 SFF Desktop PC, all they state is the motherboard form factor is, 'Custom'.

Same thing for the DC7700 USDT Desktop PC.
Both of these desktop computers are of the 'Pizza Box' design.
(Flat rectangular box)

The DC7700 CMT model is a tower model, and the motherboard form factor for it is uATX.
uATX can also mean Micro-ATX.

The form factor of a Micro-ATX motherboard is 244mm by 244mm, or also said as 9.6 inches by 9.6 inches.
(9.6 inches is approximately 9 and 9/16ths inches)

To regress for a moment, and explain the term Form Factor.
This term is supposed to apply only to motherboards, but has gone on to apply to computer cases, and power supply's.

Form factor means the dimensions of the motherboard, and also where the I/O area is located.

[I/O = Input/Output
Area for the Input/Output devices that are attached to the computer.
Examples: Mouse, Keyboard and Monitor]

Whether the motherboard is installed onto the Left side of the computer case, and the I/O area is on the Left side also (ATX , Micro-ATX, and uATX form factor),
whether the motherboard is installed on the Right side of the computer case, and the I/O area is on the Right side also. (BTX)

Dimension sizes:
ATX is 305mm x 244mm. (12 inches by 9.6 inches)
Micro-ATX is 244mm x 244mm (9.6 inches by 9.6 inches)

Above the link is the Maximum size for the Micro-ATX form factor.
It can also be the Minimum size of 171.45mm x 171.45mm

(Or 6.75 inches by 6.75 inches.
6.75 inches = 6 and 3/4 inches)

Point of all this?
The motherboard form factor inside a DC7700 SFF is probably a uATX form factor, and is 6.75 inches by 6.75 inches.
Or some variation thereof.
It's a custom size.

This means good luck in finding a computer case you can buy off of the shelf, and is large enough to install an ATX power supply.

You can get a custom one made, and you're probably looking at $150 to $200.

Or, you can modify one of these computer cases VERY easily,


The above is an Acyrlic plastic computer case. It's approximately 1/4 inch thick for the case walls, bottom, and top.

VERY sturdy.

It has metal Standoff's that are set up for an ATX motherboard.

It should have holes in the case where a Micro-ATX motherboard can be mounted, by unscrewing the Standoffs, and screwing them into the Micro-ATX holes.

[A Standoff is a piece of metal that is hex shaped, and has a threaded hole in one end, and a threaded end on the other side ]

If there isn't the proper holes for mounting your motherboard, you make the holes.
The case is plastic.

Uses an ATX power supply.
The cost of the case is $50

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,

Hi i have a acerpower fv celon d running windows 2000

You should be able to change your tower case as long as the form factor is the same as the motherboard you have. The form factor is the description. Example: If you have an atx motherboard then you can remove it from your old case and install it in an atx case. You can do a google search on the make of your motherboard and this should give you the specifications. In order to find out what kind of motherboard you have you can remove the side panel of your case and look inside on the motherboard! Make sure you don't touch anything inside the case as you could do some damage, this relates to static discharge, I won't go into that now though. When you look at the motherboard the make and model number should be printed somewhere. Once you have these details do a google search. If you are able to locate your motherboard details online there should be details on the kind of hard drive you can install. I don't know if you have an old motherboard or a new motherboard but the ports on the motherboard for a hard drive are normally IDE (Integrated Drive Electronics) parallel port or a SATA (Serial Avanced Technology Attachment) port! The sata port is easier to install. You should be able to locate these details online once you put your motherboard make and model number in. You can of course post all the details here and someone might be familiar with that motherboard. Good luck. Andrew

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

Hi peju90,

If you've gutted out the old dell computer, then your only talking about a empty case. Put all the right chips and cpu's that the Asus board requires, and you should have no problem with the CD rom or any other hardware. Except if you try and put the hard disk from the dell, it will not have the same configurations, and probably be a bit crazy. But, reformat the drive to it's new board, and your home free.

The power connections will be the same as it was on the old Presario, if you have the old power supply then nothing changes on that. You'll need to hook up the front connectors for USB and Hard drive lights, reset etc, but that would be the ugliest senario. Meaning the csse fit a special connector that the board doesn't carry. In that case you to option, either cut the special connectors and replace them with the ones from the old Presario case, or don't connect them, all but the power, you're gonna need that hooked up, one way or the other.

But, that's as tough as it gets my friend. A case is a case is a case.

Good Luck
