it'll make all this difference, if you can afford a high capacity go for it, install ur os to this and use the wd for storage.

Looks like a fair build 2 me. Here are a few things I might change.

1. Get a 600w or 700w power supply.

2. Maybe upgrade ur cpu slightly to match that R9-290.

3.Get 1 or 2 more fans.

Otherwise you are good 2 go.

man if u just but an ssd in this build, it will be awesooooooooooooome.
