Thanks folks.
ImmaPC: as already stated there will be no upgrading. This is not a computer as much as it is an experiment in design. When it's complete (which will be soon) I will start a new project (whose parts list I've included below just for you).
JUST A TEASER:
Anyone who has ever sleeved an ATX plug knows its a pain in the ass...when you have a half inch of wire to work with it becomes a painful... when you then have to cut, crimp and solder the pins onto the little stumps it elevates maddening... if not enough - getting the ATX plug onto that mess could drive a man suicidal... and don't even get me started on the soldering end.
Suffice to say - won't be doing this again with a ribbon cable!!! It made the process about a million times more difficult.
The ribbon cable will be
coated in black rubber so as to keep things perdy.
More soon. I need to run the 12V power and make the ATX power black, amung other things.
Tune in tomorrow kids - same bat time; same bat channel!
A small taste of things to come:
This is the parts list for my upcoming project (starting later this year).

5 automated cooling loops
10pumps
8rads
64gb ram
16 cpu cores
4 gpu cores
*grunt grunt grunt*
Many moons away still though.
