That’s a solid PC build right there.

Some potential tweaks you could make:
- Case - go with the Raijintek Arcadia if you prefer that style. With the current setup, you get two fans, but the Arcadia only comes with one, plus the Zalman Z1.
- GPU - maybe look at a Gigabyte model with a longer warranty. Just so you know, the 270 and 270X are essentially the same card; the "X" version is just slightly overclocked out of the box, though you can manually overclock the standard 270 too.
- Power supply - an EVGA 500W Power Supply.
- Cooler - if you aren't planning on overclocking, the Spire Kepler from $27 should suffice. However, if you do plan to push it, you might want to step up to something like a Cooler Master Hyper 212 Evo.
- You can ditch the burner if you don't strictly need it; you can always burn Windows onto a USB drive instead.
It’s honestly worth investing a bit more in a good cooler.
