Point 2: Leave the side panels off like I tend to do!

I do, but that's mostly to make it easy to perform full backups. The machine
run coolers, though it spews more RF, which keeps atomic clocks in the same
room from synching.

By the way, check the CPU cooler occasionally. Mine hadn't been cleaned
since I bought the computer over eight years ago, and you cannot believe how
clogged with shmutz the heat sink was.
