Just to confirm, that's this system:

We could ask if lenovo will give us one, but if not we could pull a
Jens.  [the backstory is that when Jens was doing queueing in the block
layer, there were lots of SATA devices that didn't work quite right but
you couldn't tell unless you actually tried them out.  Getting
manufacturers to send samples is rather arduous, so he took to ordering
them online, testing them out, and then returning them for a full
refund within the allowed window]

It looks like Lenovo has a nice christmas returns policy:
