I want to upgrade my SLIM CASE DELL inspiron 530s cabinet.
But i don't know that it is ATX or something else.
So please advice me
Are you upgrading the chassis to one that is mid-size or full-size ATX form factor?
The Inspiron 530s system board is microATX form factor so the upgraded chassis must have the mounting standoffs placed in the correct locations on the system board tray.
The SFX/TFX power supply will need to be replaced with a standard ATX (a.k.a. PS2) form factor power supply unit.
