ya only the tower would be of any use. i opened it up to look at the RAM only 512mb sadly, but i imagine i could also use the PSU since im just making him more of a media and internet comp
You need help finding components? For starters or for internet use and stuff similar, start with these...
$140 i3-2120(Performs almost the same as First Gen quad cores like C2Q Q9550)
$80-100 Z68 MoBo(Dont need expensive MoBo when you ain't OverClocking or playing high end games)
$20-30 2x2GB RAM(2GB of RAM is enough for multi-tasking)
$30 250gb 3gb/s 8mb cache(250GB should be enough and will last few years B4 200GB is used if you browse and play little games like WC3)
$20 Optical Drive(Dont really need one but to install windows, Everything is mainly portable to USB but cant install windows from USB)
$60 VideoCard(You can get a GT9800 for about $60 with 512MB)
