New here with a new system

Hi everybody I hope you are all doing okay,

This is my first message and I would like to show you my new system, I did not buy anything yet, so I am waiting for any final suggestions or final thoughts.

Any suggestions or comments are so welcomed

Dose anybody know if Logisys case will fit the Apevia power supply or not?

Also it was very hard for me to find any CD burners with a SATA interface, I wonder why

I heared that windowsXP proffessional edition is not a good in gaming is this true or a rumor, and what is best WIN XP home edition or pro or media center, I will be new for XP I have been using Win Me forever

Is there anything could be missing to just get the system runing for the first time???

Too many questions
Thanks
