Hi Bruce, Indeed I did mean the dual-500, and indeed it is a Gigabit Ethernet model. My previous email (just sent) includes a link to the specs page. OWC charges $33 per stick of 512MB PC133 or $32 for PC100, which is not bad at all... but, I was hoping someone might have some used memory taking up space in their closet that they would want to get rid of somewhat more cheaply. =) The same goes for the video card... a brand new ATI Radeon 9200 is about $120, but I'm hoping someone might have one they no longer need. (An even older Radeon may also work, but I think it has to be an 8000-series or higher to support 1680x1050 via DVI. A 9000 from an MDD would work perfectly, and nVidia is probably also OK.) Thanks for the info! --- Amir On Sun, 27 Jul 2008, BSugarberg wrote: > Hello Amir, > > If by DP500 you mean a dual 500 mhz CPU, then you have probably have a > Gigabit Ethernet.
