Welcome to LQ. We were all newbies once.
There are several US vendors of native Linux machines:
Zareason,
ThinkPenguin, and
System76. There may be others I haven't heard of (not counting Dell, which offers Linux on some of its machines).
Me, I have three Zareasons and have had excellent experiences with their warranty support. I have also had good experiences with ThinkPenguin. My Zareason laptop has the best laptop keyboard I have ever used.
I've had no dealings with System76. I've heard good things about them, but they are too wedded to Ubuntu for me. Zareason and ThinkPenguin allow you to pick your distro.
Just my two cents.
Also, there's no such thing as a stupid question, until one asks it a second time . . . .
