No. The PCI slots on the motherboard will not line up properly with the chassis and most chassis that are made for ATX have screw holes to accomodate atx and mini atx
No. All ATX cases are capable of accepting a microATX or FlexATX motherboard as well.
no
FlexATX smaller version of MicroATX
usually any motherboard that has a form factor above mini or micro atx (atx, extended atx, super atx) will have atleast 4 if not more expansion slots available by default and normally an atx (and possibly a extended atx) motherboard should fit in a full tower case (a super atx motherboard will more than likely need a super tower)
Yes, if it is an ATX motherboard. The motherboard specifications should say specifically if it is ATX, mini ATX, BTX, ITX, etc. Most motherboards are ATX.
Two common types of motherboard are ATX and Micro-ATX. An ATX motherboard is much larger and allows for additional hardware to be installed.
Asus is simply a manufacturer that makes atx and non-atx motherboards. Whether a motherboard is ATX or not is specific to that single model.
It is an ATX motherboard. But even though it is an ATX size it is a company specific motherboard, and is not compatible with standard ATX cases.
Micro ATX
flex ATX above that is the micro ATX
There are many differences between AT and ATX motherboards. The most noticable, without disassembly, are probably the keyboard connector (AT is much larger) and the power switch. The power switch for an AT motherboard clicks on and clicks off. The power for an ATX motherboard is a momentary push button that is always open unless pressed. Internally the best indicator is the power supply connector to the motherboard. An AT motherboard uses a two piece single row connector. An ATX motherboard connector is one piece with two rows of ten connections.
There are too many types of motherboards, you must be more specific. MTX and mini ATX
