Software RAID is used and recommended all of the time for people and orgs that can maintain it.

What type of maintenance is required for real software RAID?

Maintenance as in "oh shit a drive died, what do I need to do?"

Because hardware raid makes this stupidly simply, pull the drive, install new drive let it auto rebuild. Software raid requires you to mark a drive as bad, eject the disk from the array, shutdown the server, replace the drive, mark the new drive as a replacement and then rebuild the array.

Just different management/maintenance process.

I think everything but shutdown the server. I was able to replace a drive hot with MD-RAID on my little test box.

@dustinb3403 Ah, gotcha, I didn't know if there were other aspects to managing the array that I wasn't aware of. If it's really only when a drive dies that's not too bad. I've been thinking about getting some refurb hardware for home and would love to skip the expensive hardware RAID cards.

Each system depends, you might have blind swap capabilities.

But you contradicted yourself from other posts though...

None. Same as hardware RAID. RAID isn't something you touch until you replace drives that have failed.

All enterprise RAID is hot swap. No "business class" software RAID requires you to shut down the server. That's FakeRAID only.

WIth Software RAID and Hardware RAID

In what way? I've always said software RAID is faster and more enterprise, hardware RAID is simpler and more applicable to the SMB.

What are you going to run on it? KVM?

Yes, KVM

Then yes, MD RAID is built in and will work great. Only thing you lose is blind swap. Other than that, you get a faster, more enterprise system. And as it is for home, you don't have to worry about handing off drive swapping tasks to junior or bench staff.
