All true. 24 channels, 44kHz and 16bit should not cause problems on any mid-recent machine. I routinely handle sessions with 24 channels, 48kHz, 24bit. Mostly about 6 busses. CPU-usage can then be a bit high if you have dynamics and an 8-band-parametric EQ on every channel + cpu-intensive plugins (ir_lv2, ...) on the busses. Just try it out and you'll see how your CPU can cope with the DSP load. Of course more RAM is better since you can cache disk-reads but as Paul said: any recent machine should be able to get the work done.
