Parts Express has a 54" tall pro-sound equipmenet rack, "400 lb capacity", 11 gauge steel rails & 14 gauge steel top/bottom, for $240 + shipping.    Add $47 for four casters (2 locking) OR $110 for skirted base + four non-locking casters.    

Very reasonable but thought I'd check for alternatives before pulling the trigger.   Mouser is a lot more expensive (might be better quality).

Thanks all.

Another good place to check, although I don't know how they compare in prices, is markertek.com.  

Be aware of ground loop problems that can occur from rack mounting consumer gear.  If earth ground is tied to chassis and signal ground is tied to earth ground via chassis you are going to introduce even more ground problems with providing another path from ground to ground via the conductive rack.
