Allan, Thanks a lot for posting. Is your GeForce2 MX an upgrade item too? Is it the GPU with a big or small heatsink? Is it (also) fanless?

I may have a bad board or am stressing the cube with the PL 1.4, 120GB Seagate 7200 drive and a GeForce IIMX, because sometimes the cube unexpectadly locks up. It may be a SW issue, however, I don't really know. Usually if it locks, it locks during heavy operations (often while using Nikon Capture, which I originally thought was the cuplrit), but sometimes it has locked up while completely idle. Before I blame the upgrade card, however, I plan on reinstalling panther to be sure I don't have an OS issue, and maybe even puttging the Rage128 back in. Allan
