Dimension C521

[sparker781]

Is it possible to move my PC hardware from my Dell C521 tower from this:

into a mid tower case....If you look in the middle picture on the lower right hand corner that little blue plastic piece is gone and therefore if I install a new videocard there is nothing there to stop it from wobbling....

Thanks

Measure the motherboard and refer to the chart on the right of this page. It is in millimeters.

Find your form factor. Most cases today support ATX and/or MicroATX. If it is not one of those, you might have to do some hunting for a compatible case.
