problem removing a Dell Motherboard from the case

[simonchipmunk]

A friend brought a Dell computer and asked for help to replace the Motherboard.
I removed all the screws from the motherboard.
but it would not budge when I tried to lift it out.
all I know about this computer is the case was built in 2004.
I can only remove the side panel and the front panel from this Dell.
the drive cages are screwed into the back panel and front of the case.
it is a sturdy case.
does anyone know how Dell fastens their motherboards to the case?
should we junk it?

What is the model number of the computer? Service tag number?

What is the model number of the computer? Service tag number?

LCN-OF5949-70821-460-COPW
the product NO. is 411/26100004
this all I could find on the Motherboard itself.

ubrales: I don't see any standoffs holding it down.what is different about this computer is there is a contraption that covers the CPU, and it leads to a fan that apparently blows out the air from the CPU, to the outside.

I finally found the Service Tag: BD9CK51
Express Service code is; 24746368501

This is a large curvy green thing?
If so, that is merely an air duct. Sucking hot air off the CPU heat sink and blowing it out the back.

Here is the manual - ftp://ftp.dell.com/Manuals/all-products/esuprt_desktop/esuprt_dimension_desktops/dimension-2400_service%20manual_en-us.pdf

I got it from "support.dell.com" after I entered the Service Tag Number that you provided. The motherboard does not have stand-offs; instead, the back plate has bumps; functional.

Personally, this computer is suitable only for emails and word processing. I have an old one that I am willing to give away. The drive is PATA, and it has a CD drive, not DVD.

oooo...a 2400. I had a couple of those.

As said above...not good for a whole lot.

ubrales: thanks so very much!!!! I found the manual at the link you posted and now know how to remove the motherboard. I don't like Dell computers anyway.My bro a computer engineer,says Dell uses used parts for its computers. The only good asset about this one is the case.
