Im going to get a QX6700 or QX6800 - i think I can do with the quad core for HD editing and some VSTis/Music production.
My question is really whether this will fit in a MicroATX case with
basic 3d video card
advanced PCI audio card with midi such as the upper end M-Audio PCI cards
lan/connection card - not sure if I need a modem card - Ill be using the PC with Lan cable
also I need a power unit for it that will allow me to use the computer in Europe or America - this is standard switchable - correct?
whatever else is necessary
Do you think this will fit in the microATX case fine?
Who around NY or the US can I order one from? I've been searching for ages for a good custom dealer.
You should be ok with MicroATX. It doesn't sound like you're going to OC your cpu. Most modern mobo's have onboard lan these days, odds are anything that supports those quad cores you're looking at will have them. As long as you don't need more than 4 slots you should fit everything in. Also, some mobo's have built-in firewire in the rear and headers for front panel firewire as well.
