This one pushes the budget a bit. Here are the advantages of the parts.
- The quad-core i5 offers great performance out of the box
- The motherboard is of the newest line of non-overclocking boards.
- 8 GB of RAM is standard for gaming and office use. You don't need more unless you're running a large server.
- 1TB of storage is standard for desktops, and will allow for plenty of space. It runs at 7200RPM. which is the current standard for hard drives.
- The video card is an excellent card at a budget price. It'll play games like Battlefield 4 at High-Ultra settings.
- Case is simple but functional, with enough space for all of your needs and decent cooling. I've built with it before.
- Power supply is a quality unit from a reliable brand, and 550W will suit your needs well.
- Optical drive is simple, cheap, and fast. I have it in my PC. It won't do bluray, that'll cost a bit extra, but it does CD/DVD.
- Windows 7 is my preference, feel free to get Windows 8.1 if you disagree.
I'll have a second cheaper option if you'd like.
