Picked this up used on Amazon for $130, and am eagerly awaiting its arrival to be in "very good" condition, as was indicated by the seller:

Lenovo ThinkPad T510 Intel Core i5-M520 2.4Ghz 4GB RAM 250GB (SSD apparently!) 15" LCD Win7

Any recommendations for what to install on this fairly old laptop (believe circa 2010?) in the year 2017?

I've heard OpenBSD runs great on the older Thinpads, so considering that, or potentially something like TrueOS, but am not averse to venturing toward the likes of Antergos... I'd even by down for Puppy Linux...

What are people doing in 2017 on their older Thinkpads??
