I have one of the higher end IBM A31ps. It has a 1.8GHz P4, a 60GB 5400RPM hard drive, 256MB RAM (upgradeable to 1GB), S-Video In and Out, Firewire, 1600x1200 LCD (great for all those stupid palettes), ATI FireGL 7800 w/ 64MB video RAM. Premier runs pretty well on it. It would be nice to have a faster drive, but they don't make 7200 RPM 2.5" drives so you might want to consider an external firewire drive. I haven't actually tried to do any serious editing on it yet. The only time I tried to edit on the machine at all was before I installed HuffYUV and the hard drive isn't fast enough to play uncompressed video in real time so it was rather painful. The video out works pretty well, but I haven't tried the video in.
