Hi there.
First of all, it’s my first time posting here, so I don’t know if this is in the right place (feel free to change it)
So I’m thinking of building an HomeLab for storage, media and probably trying some smart home stuff. I was thinking of using my old rig to it but I’m here to ask you if you guys think it a good ideia or if I should sell it (trying like 400€) and build the NAS Killer 6.0.
For your stated purposes, it sounds fine. To expand storage, you’d probably want a case with more bays such as an N400. And personally I’d just ditch out the AIO for an air cooler like maybe a Thermalright Assassin. Can also remove the GPU to save the energy, doesn’t seem needed for server purposes.
We typically try to steer people away from cases for their servers that max out at three drives and also from putting their servers in cabinets or furniture.
They’re there to connect more hard drives than the motherboard can handle with its onboard ports. If you’re installing in a case that can only take three, the mentioned motherboard has enough ports for three SATA drives.
Unless you care to use SAS drives. Then you’d need to add an HBA to use those.
I would advise against trying to just stick a HDD in a case not properly secured in a 3.5" bay, at least not long term. Vibrations are the bane of spinning rust drives.
