In hospital. Had some cardiac symptoms around 8 last night, went to the ER, and it looks like I'll be here thru at least tomorrow. So it's not easy to post on the Samsung.
Nevertheless, I'll leave some nagging here to tide everyone over until I've got a real computer again. Until then...
Make your cases bigger!
No, you really don't need mults in a small build.
ALWAYS overspec your P/S current by 25% over your expected current draw.
Start your build in a cab that you think is too large...because it probably isn't.
Back in a day or two, hopefully.
