The USB hub will work just fine, my wife has that configuration on her Cube. I don't remember if you mentioned what graphics card you have in yours, tho'. The standard Rage 128 card won't drive the 20" which sounds strange as I'm running a 22" Cinema display on mine but the 20" display has more/too many pixels and needs more video RAM. I think it cost about $80 for an MX2 card. -- Speak softly, study Aikido, & you won't need to carry a big stick! Marine mammal, dog & Bengal cat pictures @ <http://homepage.mac.com/dflory>
