Actually most of the stuff you will need will be based around the motherboard you pick and what it supports in the way of the CPU RAM etc etc When you have got that info then go to the specific device manufacturers and get compatibility answers from them.
I don't know what you prefer in the way of motherboards but just post in the section mentioned and you will be flooded with ideas and info on them. Myself for instance prefer Asus or Gigabyte as I have used both in builds and have friends who also like them. I also know that of brands that folks have had a lot of trouble with and another thing is it is good to get one that has good support because on the whole it is often not that crash hot.
I remember you from before. I'm sure I showed you the perfect install compiled in Clean Reinstall - Factory OEM Windows 7 which is based on what's worked best in tens of thousands we've helped with here.
Unless there is some problem with your hardware then you should have a perfect install to the exact extent you stick with the tools, methods and optimizations given in that tutorial.
You can test your hardware and then go over your install using the Troubleshooting Steps for Windows 7
I don't know of a site with that specific purpose. Do the best you can and post a list of the parts you are considering on this web site in the "PC custom builds" section before you commit to buying anything.
The heart of the system is the CPU/motherboard/RAM combination and they must be compatible with each other---an Intel socket 1150 CPU will fit only into a socket 1150 motherboard. The RAM is likely to be DDR3 of a certain size and voltage. Etc.
