I'd go for the P180 execept for that air duct.
AntecCSR, is there a filter on the CPU / vid card cooling duct? Also the positioning on the P180 is a little strange - it's taking air in from the back, directly above the exhaust from the PSU! Now that can't be good! Not a problem on the Sonata II with the PSU at the top, but on the P180 aren't we taking the hottest air exhausted from the system to blow on the CPU?
