I've got an antec 900 with (what was about a year ago) a mid gamer spec PC.
I'm not into modding really, I just like a smart and functional build with decent, good value components.
So nope the Antec is not painted! Nor are the cables hidden behind the mobo. They are cable tied to make airflow better, but I dont need that too much as when i'm not gaming my chip fan (AC freezer pro 7 on Core2 6320) doesnt even come on!
I do build all my own PC's though so i appreciate the work that goes into a decent build!
