> 1-Regarding OS, is "Fedora Core 64bit" a good option for AMD Athlon 64 X2
sure. distros are just desktop decoration, and anything recent will
perform equally well. you do probably want 64b, but that's not rare.
> 2- Is SATA II HDD compatible with Fedora Core 64bit?
disks don't have compatibility - controllers do. so it depends on your
motherboard choice. but I haven't seen any builtin controllers that
don't work well.
> 3- Concerning RAM, is "2 GB 800 MHz DDR2" sufficient?
any general answer is wrong. 2G is a huge waste of money for some
applications, and not nearly enough for others. you'll pay a noticable
premium for ddr2/800 as opposed to ddr2/667, though, and might not
notice the difference (again, depending on your workload).
there is only one general correlations I'll draw: many, many loosely-coupled
and/or serial jobs have tiny memory footprints (so 2GB is overkill, and since
the cache is effective, higher bandwidth is wasted).
it's hard to say anything useful about tighter-than-loose parallel jobs,
since memory size/intensiveness varies a lot - moreso than for loose/serial,
at least in my experience...
