Even better, one of those compound miter saws used for cutting trim.  The fine pitch carbide blade works really well on aluminum extrusions and tubing.  

The practical advantage of the circular saw type blade over the band saw type is that the blade is a lot more rigid, so you get a straight cut.  Bandsaws and hacksaws have flexible blades and some amount of practice is needed to get really straight cuts.  A handheld sabersaw works well on aluminum panel (get a "bimetal"blade for good results on medium thickness aluminum).

(Mind you, i've stopped making my own panels ever since I found out about frontpanelexpress.com... Weird cutouts, tapped holes, anything you might want)
