Never ever purchase a computer from Velocity Micro. I payed 3 grand for mine. They are actually Sager computers but Velocity Micro builds them. When I first got it it worked for a day then the screen wouldn't come on. Then half my RAM stopped working. Then my video card failed. Now its shuts off at random and says Operating System not found. I may not be online in the near future cause I'm about to throw this bit*h off the balcony. High Performance computer my ass.
