Ideas for custom SFF case

[Pjalchemist]

Im going to give the SFF route a go. I've picked my hardwear being

6950
ITX Z68 (Zotac if they fix there oc issue or hopefully someone better comes out soon)
8 GB DDR3
2 SSD's (2.5'')
Maybe 1 3.5''
Slot loading slim drive
600w PSU

Plan is to water cool it all using an external setup i currently have.

I been toying the the idea of having it with the GFX card vertical with ether port on the top or base.

Wanting to make the unit as small as possible really.

Just wandering what other ideas people have come up with?
