psu - you can pick up an extra value, BUT alot of people go on how important it is to have a decent one (i'm not saying true or false), so you might want to get somthing solid like an antec earth watts one
optical: DVD R and DVD RW ~ £8
that's your basic comp. let's see pricing
140 + 60 + 50 + 80 + 55 + 8 + 50* ~ 440
*estimate for a case and psu
you can get a cheaper CPU (amd triple for £105), board ~ 30 squid and use DDR2, where you can get 4gb for under £35, that will knock 80 of build cost.
also maybe an artic cooler for £14 (probably cheaper than that now).
you might be scared of building your first pc or some people might say it's really complicated... it's really not. there is no soldering or anything, just simple plugging a connector into another. it's safe, cheap and easy.
hello,
dude its really not that hard to build a computer, took me about a week to learn (i was 12 at the time i first learned i'm 13 now). just do some research on the internet. a buncha guides are available, i can direct you to some if you want. also its a lot cheaper to build one yourself and you can brag about it to people you now . you can find a lot of good computer on ebay for cheap, only issue there is shipping.
