Do you realize this is a baby workstation wannabe? No ECC, first x16 slot blocking x1 slot below it. Motherboard is socket 1155 means 16 lanes regardless. And 2 more legacy PCI that is not wanted. Motherboard does not support any SAS drives without controller. Problem is most of SAS HBA cards are usually x4 or x8 PCI-E.

Do you realize it's a good idea to do some research before you start typing?
Not all E31's are created equal. The CPU in this unit (a full tower case, nothing 'baby' about it) is a quad-core Xeon E3-1225 v2. Specs are here.http://ark.intel.com/products/65733/Int ... e-3_20-GHz
Had you bothered to research IBM/Lenovo machine type code 2551, you may have discovered this. You might also have discovered it does indeed support ECC memory.
Thanks for sharing your (heartfelt, obviously) opinions, but why did you even bother? It is clear to me you had no intention of providing a relevant, helpful or informative answer at all.
Oh, and you do realize this is not a Dell forum, yes?
A great many people (myself included) have tried several Dell computers, including their servers.
I can't speak for others, but I've certainly made my choice.
