It's 1100, but it's what you asked for. You can cut costs by going for a cheaper case (you'll probably skimp out on wire management and get bad thermals, so I wouldn't), skip the disk drive (install windows via usb), downgrade the chip to a 6300 (I've heard great things, but it's ultimately up to you), or ofc, drop the 2nd monitor.
