Alphacool HDX5 keeps a pair of M.2 SSDs cool
 

It's been a long time since I've run out of SATA ports on a new build, but it still happens in home servers and NAS boxes. If you happen to have some M.2 SATA SSDs laying around and not enough sockets to throw them in, Alphacool could help you out. The Eisblock HDX5 SATA RAID controller isn't the sort of product we usually see from the German group, but it's actually named for the giant heatsink that covers both sides of the card.
