Your Inspiron 531S has a microATX mobo, but is an NVidia chipset while the GX270 (ATX) is an Intel chipset. So it's hard to say. You should be able to remove the rear header plate and use it in the other case, but the front panel connectors are probably not going to match.
Hey guys i've just obtained a dell Gx 270 mini tower from a friend and i was wondering if i could take the components out of my inspiron 531s and i put them in the Gx 270? Would there be any problems doing this? It will really help if anybody can help me. thx
