I've built a few PCs over the years, but always from bargain second hand parts. The trick is to know someone else with more money than you who upgrades often. then blag all their castoffs for a low price/ a few beers. Sure, you don't get up to the minute hardware, but it'll run se4 nicely and you'll be able to save your pennies for the occasional killer graphics board/ ram upgrade.
