It is hardware RAID however it's limited to HD's of 2 TB while the total RAID size can be 6 or 8 TB? don't remember. I do know that it's limited to only RAID 1 and RAID 0 which sucks so only way I will be getting RAID 10 is if I get a card for it. I do have some Arctic silver I was thinking if it would be worth trying. Also the strangeness that I would have to interact with the riser board and remove that out of the motherboard and put it back in. I would have to be careful. I just got done cleaning all the fans and heat sinks more thoroughly. The whole dell shit will be a pain when it comes to introducing foreign hardware like custom coolers and fans. I think there is a way to get it all working no matter how ugly it gets. Hell last week I slapped together a cooling solution for one of my external hard drives that just decided out of the blue to hit 54 degrees C by slapping on a cooling assembly from an old Pentium 4 machine cardboard plastic from broken DVD cases and lots and lots of electrical tape it looks absolutely hilarious and ghetto. I am proud of this abomination I slapped together and it works damn good too went down to 30 degrees C lol.
I wish I could use this machine as a server It's extremely hard to find an internet connection that is above 1 Mbps up. Sucks hard. Unless I move to wherever they have Google fiber at.
