Over the past couple of weeks I've been running lots of Google searches to find an answer to this question however I'm pretty confused. There is no simple answer some people are saying it is ATX whilst others are saying it is mATX! I'm hoping to trash my current case in favor of a better one that is better built.
My PC is a Packard Bell iXtreme M5800 I've modified almost everything however it still has it's factory motherboard and case. Any help is very much appreciated and please feel free to ask questions about any other information you need, thanks!
