stary komputer -jak go unowocześnić?

Witam serdecznie,

Mam stary komputer. Z grubsza:

Duron 800, 640 ramu, GeForce32DDR PCI, DVD, CD, kamera, skaner, drukarka
- ogólnie wystarcza do Internetu i prac biurowych.

Mam jednak pytanie jak mozna go troche unowocześnić. Nie inwestujac za
wiele. Jaki max procesor moge to tego włożyć? Jaki wiatrak? Moze zmienić
kartę? Moze dodać pamięci? Byle nie przeinwestować. Myślę, ze tak góra
do 250-300 zł.

Sporo o sprzęcie poniżej. Dzieki.
