mATX in an Antec 300?

aharvey · Oct 14, 2008

will a mATX board fit in an Antec 300? on newegg, MB compatibility only shows ATX. since mATX is smaller, does this mean it will fit by default or will the standoffs not be correct?

matx tends to fit in ATX cases. Sometimes you have to re-arrange the standoffs, but i'm yet to see a case where it didnt fit.

You can install standart ATX and mATX boards according to this from the Antec site:

Impressively spacious and unbeatably reliable, the Antec Three Hundred is an unbeatable enclosure. The Three
Hundred has enough room for an NVIDIA 8800 series graphics card, as well as six hard drives and a standardATX
motherboard. A cable management compartment keeps your system organized and the airflow unobstructed. A
120mm rear fan and 140mm top fan ensure that the case runs cool even when playing the most demanding games,
while the sleek black finish gives it an extra stylish edge.
