So I have a Velocity Micro tower with a decent power supply and a basic dvd rom. It was a tower built with windows vista on an intel 4 platform.
I have since removed the gpu, motherboard and cd rom.
Now what my questions are is as follows.
If I buy a motherboard, CPU combo will the cpu be mounted?
If I buy a motherboard and cpu and gpu separately, other than the gpu slot what compatibility issues do I need to look out for.

I do know how to put silver on the cpu for the heat sink but do not want to do this.


Also and finally I am very low on money since loosing my job. I have donations coming in VERY slowly on my stream from my laptop but need a bigger rig. What sites or brands do you recommend. I have tigerdirect and newegg in mind but know that theres better options. I just don't know where.

Thank you all so much in advance.
