I don't know what your exact price range is, but thats all quoted from newegg.
But It depends on what you want in your computer. Thier are certain factors you must look for when building. For example, pick out the motherboard FIRST! I find this the easiest, that way you are limited to what hard ware componenets you can use and your not trying to look around after all the components have been picked out for a motherboard that is compatible with your; case, processor, ram, SATA/IDE Drives.
Then you might want a case, just pick out any of them, make sure the case is compatible with your motheboards form factor, EG, ATX motherboard in an ATX compatible case.
Pick out memory next, keep an eye on your motheboard, its only compatible with certain types, make sure your motherboard can support as much memory as you picked out.
Processors agian, keep an eye on your motherboard, only compatible with certain socket types. Quick tip: Duo core is 2 cores at the clock rate specified (EG: 3.0Ghz) Quad is 4 cores, but quad can easily run you about $1,000 At the moment, so I'd stick with a duo core, its still nice and powerful.
Harddrives! Check your motherboard agian... Make sure it has the IDE/SATA channels you need for your drives.
Video/sound cards. Check your motherboard again, usally a PCI-E Slot for video cards and a regular PCI for sound cards.
ODD(Cd drives) Just check your motherboard and makesure ti has the IDE/SATA channels for it.
Operating system, Don't have to check your motherboard for this one. Get what you want! I recomend Windows XP Professional 64bit Yes, Im getting vista becuase I already have that copy of windows and Im gunna have a dual boot, lets hope Windows can do Vista right!
NOW! After all that you need to look at powersupplies. http://educations.newegg.com/tool/psucalc/index.html
Use that to calculate how much Wattage you will need in a PSU. Also! One last time... check your motherboard, make sure it has the right connectors EG; Use a powersupply with a 20+4 pin on a Motherboard that takes a 20+4 connectors. And make sure you have enough connectors for your CD drives, Hard drives and such.
Thats my little guide for you. Hope it helps =)
