Smallest ATX case

I know nowadays people seem to be looking for the largest ATX cases they can find, well I like to be different and look for the smallest. Does anyone know of what is the smallest case you can get? I'm looking for one along the lines of a mini-ATX case where the PSU is mounted on the side of the case, which allows for the case to only be the height of the mobo. Anyone know if such a case exists?

For my last build I ended having to buy a Qtec case to fit my needs which proved to be flimsy and noisy (lots of vibration) does anyone know of some small ones that are also sturdy and noise insulated?

Longshot, but I though if anyone would know, here would be the place to ask.

I got one from Aria for £15 but it was pretty poor quality tbh. Here's the link http://www.aria.co.uk/ProductInfoComm.asp?ID=1334

To clarify, is a case that can only take a MicroATX Motherboard ok then?
What about a desktop case, where the PSU can be mounted differently, or are you looking for a tower case specifically?

Even something like http://www.scan.co.uk/Products/Produ...oductID=177654?

I'm preferably looking for an ATX case. I'd rather it be wider than it is tall as there is a space under my desk for it which has loads of width room but not height. I have seen tower case before where the psu is mounted on its side infront of the PSU heatsink. This would be ideal for me, as the height of the PSU would be completely taken out of the case. I haven't been able to find a decent one which has this setup.

you can get motherboards that are 'mini atx which are a little less wide than atx motherboards, but not quite as small as micro-atx. I don't think there are many cases like this in production to be honest. The antec p150 is a pretty compact atx case, comes with a really good psu as well.
