Well, deciding the specs is not too difficult considering there are no cost constraints.
If you need a machine for a small to medium scale server and a solid performance, the Intel P3 1 GHz on a Asus TUSL2 or even the Intel D815EEA2U is good enough. You have the option of external graphics and support of server P3s with 512k L2 cache and speeds maybe upto 1.6 GHz (right now they are available till 1.26 GHz only) or even the lean mean Celeron 1.2 GHz with 256k L2 cache (OCed to 1.6 GHz @133 FSB) that makes it almost similar to the older P3. Bear in mind the i815 chipset supports only upto 512MB od memory, no more which might impede you ambitious plans if any with this "server"!
As for AthlonXP 1600+ is the best bang for the buck, the Asus A7V266-E board is good, it even has a onboard IDE-RAID controller, but I would personally prefer the Asus A7A266-E with ALi Magik rev C chipset.
For the personal system, you might go in with a slower processor like a Celeron 1 GHz or Athlon 1.1 GHz, if you dont have any specific performance requirements, you might as well go in for integrated display with the i810/i815 for P3/Celeron or the KL133/KM133/SiS730 for Athlon.Duron. Motherboard brand is not as important for that, but make sure you get a brand board like Asus, Jetway DFI and not a noname board that comes in a plain cardboard box and you have to look at the BIOS ID to get the manufacturer.
For all its worth the integrated displays, linux is not too kind for them, it takes some effort to configure those in Linux, especially for the server. The non-integrated boards like the TUSL2-C or D815EPEA2U are good.
If you are in India or in Pune I might be able to help you in person.
