I actually just had a look at that,

Im not sure it would quite fit, it leaves only 1cm for motherboard and standoffs ets,
However, I have had a revelation, maybe, ill just go for a normal case, and just have it on its side, (when I want to be able to tinker with it.....)
So, any suggestions for a decent case then?

But one that could be watercooled at a later stage.....
