build cheap computer, need help plz
Hey everyone I'm new and would appreciate it if any of you can help me with a few questions.
I'm currently using a HP Compaq dc5000 Small Form Factor PC, yea I know old lol but I'm tired of this antique and want to upgrade to something little better. So I would like to know if I can buy a new "cheap" motherboard and graphics card can I use parts in this computer to put in the new one? I know i can put the hard drive, dvd drive etc. but what about the processor and things like that because I have never built a computer before and need some help. I have 759 ram but its ddr so I will need a motherboard that supports it or it will go to waste.
I have a $300.00 budget to work with, Thanks
