Thanks for the input guys. So how much do I really save by building my own PC? For example, I am buying the same exact system at Dell would cost me $1200, how much do I need to spend if I buy every hardware myself and put everything together myself? I just want to see whether it is worth the time and effort of building my own PC.
BTW, I opened my PC this morning and I realized I have two Memory sticks, they are 512 MB DDR 333MHz CL 2.5 and 128MB DDR 166MHz CL2.5. The inconsistant of MHz may slow down the pc? What's the max MB of ram can my Dell P4 2.66GHz handle? (1GB or 2GB?) I was also having hard time taking off the fan, I couldn't take it off. So I guess the fan can't be upgraded if I can't even take it off?
The ram will be as fast as its slowest module, so in your case they were both running at 166mhz.
As far as cost of building a new pc, I assume you wouldnt need a monitor, leyboard, etc, is this correct? Another question is what types of games do you see yourself playing?
You could spend as little as $500-800 to build a new pc that would be fairly snappy and beable to play almost any game now and in the foreseeable future
