Speaking of the G5, I just bought a MOTU 2408 mk3 (core system) and 24 i/o (expander) only to find out that the enclosed PCI-424 card doesn't fit in the G5's new PCI-X slots. MOTU has an upgrade path... if you've got an 'older' PCI-324 card, you can upgrade it to the PCI-424 card for $300. You can then upgrade the 424 card to a PCI-424 G5 card for about $70 more, and if you bought the 424 card after July 1st, the upgrade to the PCI-424 G5 card is free. You just have to fax MOTU a copy of your dated sales receipt and your registration card, and they give you an invoice number to write on the outside of the package when you return the PCI-424 card to them. They should've received my 424 card yesterday... here's hoping the G5 card arrives this month! Scot Jacob Loehr
