Building a custom pc

Hi Anon, I'm trying to build my first real gaming pc without breaking my wallet, this is what I have so far:

any advice?

Aluminium cases are lighter and dissipate heat better.

You've only got one 500 GB drive there - and no mention of backup stuff.  You might want to consider some RAID or some another drive for back up.
