To those who believe naming computers is nuts, I direct you to RFC 1178.
Cameron is my new primary workstation. She is a custom-built machine with an Intel Core i7-4790K processor at 16 GB of RAM. She runs Windows 10 Pro and has a NVIDIA GTX 970 graphics card. She uses a variety of SSDs and a pair of conventional storage drives, all in hot swap bays. She's fairly unique in using Cooler Master's HAF XB case, which makes her relatively portable. Cameron currently runs my house when I'm not there to do it myself.
Cameron is named for both Kiera Cameron from Continuum and also the character from Terminator: The Sarah Connor Chronicles.
Caroline is my television system. She is a custom-built full tower with an Intel Core i7-2600k processor and 16 GB of RAM. She runs Windows 10 Pro. She has a NVIDIA GTX 670 graphics card, a couple of SSDs, and an additional 1 TB of RAID 1 (mirrored) storage.
Caroline is, like Echo, named after the main character from Dollhouse, as well as the personality who GLaDOS is based on from Portal 2.
Widow is my offsite backup machine. She is a Dell XPS 420 with a Intel Core 2 Q6600 Quad processor and 3 GB of RAM. She runs Windows 7 Professional Edition. Recently upgraded with a NVIDIA GTS 450 graphics card, she's now capable of holding her own for gaming as well. Widow uses a WD My Cloud to back up files from my primary machines.
Widow is named after Black Widow from The Avengers.
Mari is a Surface Pro 4 I carry regularly. She's a Core i5 model with 128 GB internal storage and 4 GB of RAM.
Mari is named after Mari McCabe, also known as Vixen in DC Comics.
Kaylee is a seventh-generation i5-based Intel NUC running on 4 GB of RAM with two SSDs packed in her tiny case. Kaylee is a purpose-designed car automation computer, and has been the testbed for the automotive deployment of my home automation software.
Some of my PCs have effectively passed on by this time, but were noteworthy and deserved note of them remain here:
