Is it upgradeable?

Any body ever had a dell vostro 1000? I want to know if the ram and processor is upgradeable
I have a budget of $100 to spend on both, right now it has 1.5 gb ram and I'm trying to find out a CLEAR answer if it can be 4gb Ram
Thx

Need some recommendations too

Try Googling the processor model and ram type to find the socket/pinout you need and then order the corresponding kit and processor.
