Systems Configurator?

[Gigamite]

I wanted a new computer built for me so I went to Overclockers system configurator but found hardly any of the parts I want are up for selection. Are the offered parts stuff Overclockers are trying to get rid of and that's why there is only a basic selection?

I know the parts that I want. They are a basically a upgrade of the make and type that I already have, but the configurator doesn't offer most of the parts that I need, for instance I wanted this graphics card and motherboard.

I like the look of this case, but unfortunately it's not yet in stock.

And for storage I needed the M2 Samsung evo970 2TB.

You se my frustration with the Overclocker's configurator? It offers very few items I would consider buying.
I imagine they have most of these computers already built, thus the very limited selection. It would be nice though if you COULD actually have the computer built to your personal specs.

Thank you.
I am building this system around the new i9.
First thing is to get all my final choices linked, so I have something to give them. I wish that case was in stock though, I really like that Nuke-Coke NXZT case.

Thanks you for all your answers.
I have decided to do it myself. I have built computers before without incident, it was just that this time with it being a top build for me, I was thinking of having it done professionally. I will just take my time and do it right.
