You can view my specs then and i too only use for surfing and movies. Just got my rig from pc themes 2 weeks ago.
intel g3240 + asrock h81m-hds @$153
Kingston 1600mhz ddr3 cl11 value ram 4gbx1 @$46
adata s900 ssd 128gb @$95
wd hdd 1 tera blue @$75
lite-on/samsung odd @25
cooler master 343 micro case + c.m.400w psu @$85
Win7 hm premium 64bit@$133
ttl:$612
Buy and build @ pc themes.
$50 cheaper compared to my rig build.

oh ya btw provided the above recommendations hold stocks hor. That time i build, crucial ram ddr3 no stock, dun have lite-on ssd s900 128gb etc. and certain components such as sata odd and sata hdd from your old pc can transfer to your new build. thus u can save @100 on new odd and hdd.
