Newbie case and mobo question.

[SpyKey]

I have an old case that is described as Mini-Mid Tower AT. Currently it is holding a baby AT board, 22cm X 25 cm. My question is, if I deside to upgrade, may I consider an ATX board as a replacement? Or do I have to look for a full AT?
TIA everybody.
Case description can be found here.

If you want to upgrade to ATX then you need a ATX case and power supply .

If you're gonna get a new board you might as well invest in an ATX case.

yout AT case will not work with any new motherboard(ATX) size isn't your main issue. The power connectors for AT and ATX are different so even if it did fit in your case it would not hook up to your power supply.
