After much research, (but obviously not enough!) I have just bought a new mobo (MSIK7N2G ILSR) which is described as ATX which I understood to be a common standard for case size. It is 31cm X 23cm which as my case is only 20cm wide is a bit of a problem! I would welcome some explanation as to where I went wrong and some pointers as to what case I need and where I can get one from (cheaply)

You have a standard ATX mobo, but obviously not an ATX case.

You can pick cases up from about £20.00

Look in the back of PC mags, in PC fairs and on the internet. There are 100's of makes on the market.

It's like buying anything, there's a full range from cheap to standard to expensive to top-of-the-range.

unless you have a very modern bareone system i suspect you are measuring in the wrong direction.
the 23cm relates to the axis running from the front to the back of the case.

the atx form factor is standard.there is mini atx and atx.both have the connectors in a position to line up with the i/o shield on the atx case.

some cases only fix mini atx mobos.

buy an atx tower case and you can fill anything in long as atx.

2 points
1)I've seen lots of ads for ATX cases and they're all 20 cm wide, same as mine.
2)whichever way you measure 31cm X 23cm it's not going to fit into a case 20 cm wide.

I obviously need a case at least 24cm wide, can someone show me where there is one, I can't find any.

the mobo goes from front to back not across width wise, and I'm sorry if I'm wrong but I find it hard to believe that anyone is that dim, and suspect that someone is devining for water.

for anyone who thinks I'm being harsh, take out a ruler and see just how big 20cm is.

8 inches.....!

You can't have them both in front of you and seriously think they don't fit together.

A motherboard and case, in matching dimensions are approx

Width - case = 20cm, motherboard = 2 - 3cms, and with boards fitted 12-13 cm

Height - case 35-45cm, motherboard = 31cm

Depth - case = 35 cm, motherboard = 22 cm

What you're not doing is comparing like dimensions with like dimensions!
