I'm building two identical systems and I'm wondering how much power supply capacity I'll really need. These computers will have a very specific function and system expandability will NOT be an issue. What's more important is performance and portability. Heres how the systems will be loaded.
Intel D865GLC micro ATX motherboard
Intel P4, 3.0 GHz, 800 FSB, HTT
512 megs DDR 400 (PC3200) RAM (possibly doubled later)
1 - 40 GB PATA IDE system drive
1 - 80 GB SATA IDE program drive
1 - 52x 24x 52x CD-R
from 1 - 3 case fans.
I'm planning on NOT installing a 3.5 floppy drive unless the case I select would make it awkward not to have one. I definitely want a micro ATX case because of the portability issue. Some of the micro ATX cases I see have power supply capacities as low as 200 watts. I'm wondering if 200 watts is enough in this circumstance. I'd also welcome micro ATX case recommendations.
