I've built 2 computers before, but I still want to make sure this will work. I'm pretty sure that everything is compatible, but if someone could double-check, that would be great. I'm going to use the power supply that comes with the case because reviewers on NewEgg said that it was good enough for the graphics card and I won't be playing too many games anyway or any really new ones. So, how does this build look? Will I be able to run programs like Photoshop or games like HL2 decently well? This is going to cost me $900. Not bad, I think.
