PSU and case questions

[no_numb]

So I'm building a media centre computer out of spare parts and all I need now is the power supply. I have been advised that cheap psu's are a false economy, so the question is what is the cheapest power supply that would be recommended. This is a cheap build so the cheapest reasonable one would be appreciated.

I'm probably going to put this in a coolermaster centurion 5 case which I have lying around. However I might end up putting this in a matx case. With slim matx cases I'm assuming you need a matx psu?

My thinking and correct me if I'm wrong is that for a matx case like this:

I need an atx psu and a matx psu wont fit

and with:
http://www.scan.co.uk/products/cit-s...r-case-w-o-psu
I'd need a matx psu

Is that correct?
Can I put a matx psu in an atx full tower case or is the fitting different?

Thanks for any help.

The first one yes, it does use an ATX psu
these are some of the best images of the insides I could find http://www.agito.pl/obudowy/asus-tm-....0.336311.html

the colors-it one, I don't know, I can find nothing on it except that stock picture.
Best bet would be to contact scan and ask.

What size motherboard are you goint to use?
I am asking because there are a few itx cases in the F/S section.

Matx psu should fit into atx case as I am usinf the FSP 400w matx psu in the lian li q11, which will support a full size atx psu.

Was just using them as examples but thanks for the info. I was just assuming that the slim matx cases used matx psus but I guess its case specific.

I have a matx mobo (foxconn cinema deluxe II). Might buy a matx psu if it'll work in a tower case and possibly a future matx case.
