PSU (My 10-year-old 300W ain't gonna cut it. Not sure if jimmy-rigging 2 or even 3 together will work either....)
DVI-VGA adapter (I have 1 and need 1 more)
Budget $100 (it's all I have for sysbuilding)
I feel like I am missing something; the only thing that comes to mind is HDD; however, after finding out I can mark bad sectors, I'm going the cheaper way and waiting to upgrade.
