Flex ATX(229 x 191 mm), 小型底板, 比mATX更小 (244×244 mm)FlexATX is a PC motherboard form factor derived from ATX. The specification was released in 1999 by Intel as an addendum to the microATX specification. It uses a subset of the motherboard mounting holes required for microATX and the same I/O plate system as ATX and microATX.
FlexATX specifies that a motherboard be no larger than 9.0 x 7.5" (229 x 191 mm).

The ATX (for Advanced Technology Extended) form factor was created by Intel in 1995. It was the first big change in computer case and motherboard design in many years. ATX overtook AT completely as the default form factor for new systems. ATX addressed many of the AT form factor's annoyances that had frustrated system builders.

microATX (also known as µATX) is a small PC motherboard standard, with a maximum size of 9.6×9.6" (244×244 mm) (the standard ATX size is 12×9.6" maximum). microATX boards with integrated graphics are often used by motherboard manufacturers as a basis for small form factor and media center PCs.

(由Flex ATX) 換個底板至m ATX, 要看你的機箱大小, 螺絲為等才能確定...
但用得Flex ATX的通常是超小機箱...要放一般小的m ATX成功機會不太大..
大機箱(ATX)可放小底板(microATX, FlexATX); 倒轉就不可!
