happy to help, just remember to take your time and be careful when it comes to putting it all together, just as long as you're calm and don't panic everything should go fine. If you've got any doubts about how something should go together google,youtube or here are all full of people who've probably all done the same steps and questions before so should be able to help.
in fact one thing which I didn't think of was cooling since without a graphics card the 620might not have come with a case fan, you'll most certainly need one after the upgrades to keep all that power cooled.
Why not check me out on youtube and help me on the way to 2k subs over at www.youtube.com/stormcloudlive
