Will a m4a88t-m fit in dell case

The size and mounting hole positions of the case follow the standard uATX Form Factor so the ASUS M4A88T-M should fit.

Is the I/O Shield on your Dell Dimension 2400 case removable?

Are you also replacing the power supply unit?

Thanks for responding.
Yeah the I/O Sheild has to come out at the same time you take the mother board.
What kind of power supply do I need to upgrade to?

If you're going to be using a discrete graphics card in that system the model of graphics card will determine what power supply capacity will be required.

If you've already determined what graphics card you will be using in this system please post the information here in this thread.

Do you recommend one that goes well with this motherboard?

What CPU model will you be using with the ASUS M4A88T-M?

What is your budget for the graphics card and for the power supply unit?

I guess as suggested on Newegg I would get a AMD Phenom II and a ATI Radeon HD 5450 card since the motherboard already has a integrated ATI GPU.

The Radeon HD 5450 draws less than 20 Watts under typical gaming load.

For a system using a single Radeon HD 5450 graphics card AMD specifies a minimum of a 400 Watt or greater power supply. The power supply should also have a combined +12 Volt continuous current rating of 18 Amps or greater.

Any of the following power supplies will work with your planned system:
