If you just put it together yourself you could do it for a little over a grand.
$300 – i73770k
$200 – 32g ram
$150 – Motherboard
$150 – Video Card
$100 – for a 2tb Hard Drive (or $200 for either an SSD 128gig + HD 2tb or 2 2tb HD’s
$50 – Power supply
$30 – Dvd burner ($60 for Blu-Ray but your computer won’t be able to play movies)
$100 – Windows
That’s just $1,080 – $1,210 minus the case.
But if you’re going to build a mean machine I do recommend you get a blinged out case with a big window and colored lights. Trust me, you’ll feel better about yourself and produce better work if your computer looks as visually pimped out on the outside as it is internally 😉
