I want to make a home NAS PC and have an option to buy cheap (like in lines of 10-15€) HP PC:

  1. HP 280 G1MT (4GB, i3-4160, 180W, 3 SATA slots) from 2016
  2. HP Pro 3500MT (4GB, i3-3240, 300W, 4 SATA slots) from 2015
  3. HP Pro 3500MT (8GB, i5-3470, 300W, 4 SATA slots) from 2014
  4. HP Pro 3500MT (4GB, G645, 300W, 4 SATA slots) from 2012
  5. HP Pro 3500MT (4GB, G640, 300W, 4 SATA slots) from 2012

Don't really care for the attached storage, I would probably buy a 2x 6TB or 2x8TB HDD and boot the OS (OpenMediaVault) from a USB stick (I would have 2 USB sticks with 1:1 config on them in case one USB dies).

Which one of the HPs would you suggest? (I would prefer the 280 G1 as it's the newest hardware wise, but I'm kind of afraid that the attached 180W PSU isn't enough if I would increase the amount of HDDs in the future plus it only has 3 SATA slots so I would quickly need to buy a PCIe<>SATA adapter...)

Or is there something that I don't see at the moment that would make choosing one of those PCs in the long run as a mistake?

I would recommend HP Pro 3500MT from 2014 because it have more powerful processor, have more RAM. These things can help you when you decide to make it real NAS and to run there in containers additional software. Also good amount of RAM can help you with cashing of the data so save some read operations (and probably few write). More powerful processor can be helpful if you want to use compression to get more disk space or encryption of disks.


Agree, would also choose

  1. HP Pro 3500MT (8GB, i5-3470, 300W, 4 SATA slots) from 2014

but I would also recommend upgrading RAM. TrueNAS Core (formerly FreeNAS) now requires 16GB RAM minimum. You're obviously free to roll your own NAS with whatever OS and storage types you have available, but performance with 4GB RAM will not be as good as 8 or 16 even if just running network storage services.

  • You could also run vsftpd on Ubuntu Server and then you would be ok with 8GB RAM
