I have an old Toshiba 320CDT with the 233 Mhz processor and all. Is it possible to upgrade the motherboard/chip, harddrive, add a DVD/CD burner etc..at an affordable price or is it a lost cause? I started tearing apart the laptop to replace the CDROM (its broken) and thought I might explore the option of doing so. I'd have to be able to upgrade the chip to alteast something decent, upgrade the HD to something more than I got now, maybe put in a CD burner or DVD player (not sure if I could replace the video card?)....all for maybe about $500. If not, it wouldn't be worth the money I guess.
