I originally had this PC in a really cheap case, but then I decided to change the case,
and now my goal for this build is to make it all black and white.
You could have gotten a mini case to save space and $$$. Either get a discrete GPU or an AMD APU if you want some applications to work. i give it a neutral.
I understand there was an aesthetic goal in mind here, but you're beginning to drag on performance so hard that I'd have kept the old case and put the money towards an AMD APU. There are some pretty good ones out there.
And there are some tutorials out there on how to recolor components (cheaply). You've already gone and done it, but for future thought...
