I guess I'll have to see if I can find such an insert as it would be
nice to go with an ATX case and power supply since all of my other
systems are ATX based. My little old Socket 7 system is not that fast
and so it makes a perfect gateway/firewall system that I hope to keep
alive for many years to come.
Because it's a critical system I'm forced to keep a spare PC/AT power
supply and CPU cooler on hand for it.
