Buy now or later?

[Cyanide]

I have about $500 aus. in my bank account. And the total cost for my pc is around $2200. I will be getting money slowly as I am only 14 years old. Should I buyparts as i get enough money or buy all hte parts together when i hvae enough money?
If i should buy ht eparts asi go along, in what order should i buy them?

Given the trends of decreasing price/ improving technololgy I would definitely wait to buy pretty much everything for your computer. If you don't have a full computer any part you buy will just sit around collecting dust while the price goes down and better parts come out while at the same time your money could be earning interest either in a bank or other investments (present vs future worth... damn I hate economics). There are some exceptions - for example I don't think case fans will really improve in technology (triple ball bearing?) or really change in price, but then again they aren't too fun to have around (they don't even have a fun manual to read ).
