Extreme Media Centre Build ($4000)
What follows is what I'd build for our media centre if money were no object. I went a bit crazy without going completely crazy on hard drives (4 drives would have been a bit more crazy). This is NOT a wish list. I'm working on improving our media centre, but doing it with a reasonable budget and a bit of future proofing. This machine is the kind of machine that I'd pair with a crazy amplifier with Atmos support, decent speakers, something that wouldn't go in our apartment, but a house (we're not moving anytime soon). I haven't included an optical drive, nor a monitor. In this case I'm assuming a television. I also haven't included a video card (yet) because I haven't looked at televisions that I'd pair it with.
Personally, I'd install Linux. But at this kind of budget Windows 10 would be an additional drop in the bucket. If I were to buy one thing in this whole build (right now) it might be the sweet NZXT case!
