Go to Apple store, select the base machine...733 change the CPU ...u can choose the 733, the 867 or the dual but u dont have to have all the rest of the stuff the hiend machines have for much much less. Get 512meg of ram from a reputable dealer such as macgurus.com ....... dont buy extra ram from Apple ATTO UltraWide SCSI host controller not sure about UK stores. Dual monitor..hmm NOT an Apple LCD. The new SGI FD18 look great, have industry standard DVI and VGA connectors. Still waiting on a reply fomr Appian, they have mentioned releasing a Dual DVI graphix display card. Targon
