That is simply not true.

At our government surplus store, I can get Pentium 4 computers with 2 GB of RAM for $25.  They have SATA ports on the motherboard, so (2) 3TB SATA Seagate ST3000DM001 are $99.99 each on Amazon right now with free shipping.  For under $250, I can put together redundant server with 3TB RAID 1 storage.

Assuming you mean ProLiant 712317-001 Ultra Micro Tower Server, those cost around $400 with 2GB of RAM.  1GB/TB of RAM to storage, it will need more RAM according to:
"A general rule of thumb is 1GB of RAM for every 1TB of storage.”
