I'm looking to build my first PC to replace my aging late-2011 iMac. I had originally planned on going the hackintosh route, but after reading more into that, it seemed somewhat limiting for the money and time investment, and completely eliminated any hope of including one of the new Nvidia cards. So I switched to just Windows, which made all of my compatibility requirements a lot looser and also gave me more room for upgrades. I've already specced out a list of components, but since this is the first time I've ever attempted to build a computer, I'm not sure if there's any glaring problems that I just don't see due to inexperience.
Budget: For the computer itself, the components I have picked out now are approximately $2200, which is fine. About what a new iMac would have cost if I had been going that route. For the monitor, I can go another $1000 potentially, but I can push it a bit higher by spreading the costs over the next couple months.
Resolution: 4k (I've been looking at the Acer Predator 34-inch Curved UltraWide QHD (3440 x 1440) NVIDIA G-Sync Widescreen Display (X34 bmiphz), but that's at the very high end of my expectations and would be the "pushing it" that I mentioned in Budget).
Games/Settings Desired: WoW on Ultra; don't play many other computer games at the moment (see comment about iMac), but would like to move away from the Xbox Scorpio/PS4 Pro cycle and play any new games on the PC, preferably on the highest settings if possible; potential use for VR once the second generation of tech comes around.
Other intensive software: Nope, except future VR use.
Country: U.S.
Parts that can be reused: None.
Do you need an OS? Yes, going with Windows 10. Suggestions between OEM and full license, Home vs Professional? I haven't used Windows as my full time computer since some time in 2007, so a little dusty.
Do you need peripherals? Yes, see above for comment on monitor. I need a keyboard and mouse as well, so any suggestions would be appreciated. The cost of the keyboard, mouse, and OS don't need to be included in the mentioned budget.
