Okay, just if anyone can suggest a place:

I want an ASRock 939Dual-SATA2 mainboard.  I want this specific board because 
it lets me hold onto my AGP card and still later get a PCI-E one.  I can buy 
one online for about $74, but since it's a mainboard and as such a potential 
hassle centre, I'd like to get it locally in case I have problems.

I haven't seen it at Fry's.

PCClub's website doesn't list it.

I tried to look at RedSeven and New Technology (Frankly, they're my absolute 
last choice even behind ordering online) but their online catalogues are not 
available.

I asked in a local shop cos I was in the strip mall anyway, and they said "we 
can order it", but I to shop locally cos I want instant gratification and the 
likelihood they can give me another mobo if this one blows out.

Prefer East Valley.
