There is a difference between just getting something to work for the time being and getting the EXACT same part number. Asus mobo goes down? Who cares, I got 2 MSI's and 1 Gigabyte that will work for now!
That is pretty risky to just assume you will have the Registered DDR3 module, or the right desktop
boards. Servers use special registered DIMM's with ECC to detect and correct memory errors, and cannot use standard desktop memory.
You have dealt with the cheap-end Dell/HP/Gateway, but there is a massive difference between the server stuff and the cheap-o stuff. There is a reason Dell/HP/Lenovo service just about everyone; it is because they are dead-nuts reliable in their service and replacement parts. Dell for instance guarantee's that the motherboard you order tomorrow will be identical to the replacement part you get if it dies in 3 years.
Also, if your Asus board goes down, replacement isn't as easy as slapping in a gigabit/MSI board, drivers are likely to be quite different, and when you are losing money, the last thing you want is to have to recover your data, reinstall the OS, then bring the data back on board.
How much revenue are you expecting to generate per day? What happens if the PSU blows in the server, how long will it be down for? Going with a real server will give you 2 of them in case one dies, resulting in zero down time and zero money lost.
