size of motherboard

Just further building upon that, its dimensions are: 14 x 12 x 7 inches according to its amazon page, although i'd take this with a grain of salt, as it is a third party lister that has put up these dimensions.
Edit: Just realised it's the same page USAFRet posted! :)
It isn't an officially sold component, as it is a part of a system. Your best bet is to contact Dell and ask them directly for whatever reason you may need to know.
 
I got this desktop from a friend and I was toying with the idea of upgrading this desktop to this point of time. You know a quad 4 and what not. Just to make sure the screw holes match up with the case. Just thinking of building a home desktop, no gaming what so ever.
 


Yeah, sounds like a solid idea.
It is on the LGA 775 socket, meaning that a good potential upgrade for it could be the Q9400, Q9500 or Q9600 depending on the clock speed you want and what availability there is, hence why i've listed three of them, although you should be perfectly fine with the Q9400.
 
That (14 x 12 x 7 inches) measurements is incorrect... the standard MATX size is 9.6 X 9.6... they can be narrower or wider but the Height determines the form factor and this one looks 9.6 inches in height and apprently the same wide. You can tell from the 4 expansion slots and the lenght from the I/O edge to the mobo bottom. In ATX the I/O edge is only half way to the bottom of the motherboard. And you can only measure motherboards in H X W so what measurement would the 7 inches represent?. probably 7 centimeters to the top of the CPU fan.

 


Note that USAFRet only said it appeared to be mATX, as it is considerably smaller than a standard ATX board.
This is not a standard consumer board for seperate retail however, and likely does not have a standardized size board due to the fact that it comes from a Dell prebuilt system.
I don't know about you, but that doesn't look like an ATX board to me! :)
 


Does it work as is?
Why bother trying to upgrade anything on it? Just run it as is.
 


A lot of the older Dell Inspiron desktops circa 2008 ran with dual core processors under 2GHz, so multi-tasking current applications such as chrome and outlook for example could cause significant lag or stress on the CPU.
Its the same pain I felt before upgrading my grandparents desktop! :)
 

Where/when did I say it's an ATX?

 

*mATX.
My bad! :)
Maybe it's just the angle the photo is taken at, or maybe i'm seeing things, but it looks a little bit wider than the mATX boards i've worked with recently.....
Oh well! I guess its just easier to call it mATX, i'm probably just having flashbacks to a few non-standardized motherboards i've worked with in the past. 😵
