If you are truly concerned about your build and want to protect it, build out your power delivery this way : Wall socket --> Good Surge Protector --> Good Line Conditioning UPS. The surge protector is first in line, and will be sacrificed immediately should there be a close lightning strike/transformer blowout/etc. Even if it still works, if you see any other electrical damage in your home/office, or see the led on it start flashing/dimming, replace it. You will see stupid instructions saying to plug the UPS directly to the wall, but I have used this exact configuration in many hundreds of locations with absolutely zero problems. It has served well, with many surge protector failures, but no premature UPS failures. After all, a nice $40 surge protector is much easier to replace (or temporarily do without) compared to a $500 mid/high end line conditioning UPS. As for your build, the mobo you quote is actually a workstation board, though many use workstation boards in custom server builds. What you're doing is classic workstation duty anyway. It will be high quality regardless. I also recommend going raid 10 with 4 1TB 7200RPM Sata Drives, and buy a couple of extra ones that match so that down the line should one or two fail over the course of use, you can go ahead and drop it in with no loss in downtime or going with mismatched drives.
