Additional Comments:
I currently own a tower gaming PC. This has the following configuration:
- Core 2 E6750
- 2GB DDR2 (PC2-6400 I think)
- nVidia 8800GT

I want to make my PC easier to move around for LANs etc. I am therefore looking for a Mini ITX Mobo + Case which I could move my existing hardware into. In particular, I would like to keep my CPU, RAM and Graphics Card. I am assuming that this will require a new PSU. However, if it is possible to re-use my existing one, I have an Antec True480.

I am not too interested in the look of the case but I would prefer to have a cube shaped case.

Your options are pretty limited with mini-itx. It would be something along the lines of...

Zotac S775 Intel GF 9300 DDR2 mITX

That was the only mini-itx board with a pci-e x16 slot from both sites you listed. I'm from the US so don't know any other places you'd look.

Although for comparison's sake, these are some this is another option you have with the same board as above for comparison.

Ideally you would want a Lian-Li mini-ITX case because those cases use a standard ATX PSU letting you reuse the one you have. Some examples:

Going micro ATX will give you more options but this is what I recommend.

Thanks for the advice. I would really like to have a Mini ITX for the size but I agree that there isn't much choice and it looks like Micro ATX is a lot cheaper.

Your suggested Micro ATX case and mobo both look really good.

I ended up going for:
- Zotac Geforce 9300 ITX mobo
- Silverstone SG02B-F
