Asus Desktop Comparisons

Hey, I'm buying a new desktop for the office, and since I like Asus and Newegg I was looking at these three:

Newegg.com - ASUS Essentio CM6730-06 Desktop PC Intel Core i5 2320(3.00GHz) 6GB DDR3 1TB HDD Capacity Intel HD Graphics 2000 Windows 7 Home Premium 64-Bit

Newegg.com - ASUS CM1831-US-3AD Desktop PC AMD FX-Series FX-8120(3.1GHz) 8GB DDR3 2TB HDD Capacity ATI Radeon 3000 IGP Windows 7 Home Premium 64-Bit

Newegg.com - ASUS CM1831-US-3AB Desktop PC AMD FX-Series FX-8120(3.1GHz) 8GB DDR3 1TB HDD Capacity ATI Radeon 3000 IGP Window 7 Home Premium 64-bit

I just wanted to get your opinions on these and see if anything stands out from the rest. I'm probably going to go with the 2TB AMD or the Intel.

Thanks, FSG
