Can an ATX motherboard go inside a micro ATX case? Tags: Homebuilt Cases ATX Motherboards Systems Last response: August 18, 2009 5:24 PM in Systems Share hobbes203 August 18, 2009 6:08:49 AM The question is the title. The ATX motherboard size is 12" x 9.6" and the micro ATX case is 16.6" x 10.9" x 14.5". So I would think it could fit. Would the expansion slots line up or something?

You can put a microATX board in an ATX case but not vice versa. jbakerlent a b B Homebuilt system a b V Motherboard August 18, 2009 6:10:54 AM No, but the opposite is possible...
