I have been tempted to build a overkill custom desktop recently to install OpenNAS on and use as my home file and backup server. I had been living on Newegg in my spare time configuring $1K systems for this simple task. I also spent to much time on youtube checking out all the crazy home networks out there and then ran across a video by 8-bit guy(formerly iBook guy) about his MacMini G4 with external Firewire hard drives and his data and backup solution. It finally hit me to use my late 09 MacMini for this! I bought two 1TB 7200RPM hard drives and put them in USB enclosures and had a file server in ten minutes of setup. I am just using file sharing and screen sharing on MacOS El Capitan for this no MacOS Server. Yet.... A lot less power draw and money still in the bank account. I have had various Mini's just sitting around for the last 5 years and for some silly reason never though of this. I was configuring an i7 8700, 32GB RAM, 2 500GB SSDs with 2 2TB HDs PC for OpenNAS but my 2.53Ghz C2D with 8GB RAM totally rocks for this! Just wanted to share.
