Looking for a small pre-built PC with space for two 3.5" drives

Currently I am using an oldish OptiPlex PC (SFF) with space for one 3.5" drive. Has anyone spotted a small PC that has space for two drives? eBay purchase would be fine.


For TrueNAS you will need a minimum of 3 drives:

  • Boot drive
  • Mirrored data drives

So you will need some way of physically mounting and connecting a 3rd drive (M.2 or SATA). If you are going to buy a used desktop machines then you will need both a case and a motherboard that supports this.

You might be better off with a 2nd hand tower PC with a non-gaming motherboard (lower power consumption) with (say) 4-6 SATA ports.
