SFFPC with ECC RAM and 3 drives?

I'm looking to replace an aging HP Microserver and can't find anything similar to the old N40L. They were pretty small and space for 4 SATA drives. That's really all I need. It doesn't need dedicated GPU or wifi or bluetooth.

Requirements:

• ECC RAM
• 3 SATA drives
• Not buying used from ebay

Is there anything like that? They were even pretty cheap back then.
