Here are some peripherals that's I'm looking to part with, since I'll be selling my PC as well (which will be in an ad soon as well). I'm happy to bundle things for a somewhat reduced price, but here are the items. Please let me know if you have any questions!
Cooler Master CM Storm Quick Fire Pro keyboard – $15
This keyboard works well and I've had no issues with it, although it could use a dusting or cleaning.
Logitech G413 Carbon keyboard – $15
This was a more expensive keyboard originally, I believe, and I haven't used it in years, but I recall the enter key on the numpad wasn't working. The main regular one is, though.
Logitech G502 Hero wired mouse – $15
This mouse is very well known and well regarded, and it works excellently.
Razer Hydra – $50
These things are flipping awesome and I love them. They've been discontinued for quite a while, but they are excellent motion controls. There's a program called MCE that lets you just map controls on the Hydra to mouse and keyboard inputs. It has a learning curve for sure, but it's extremely capable. I even used it for shooters, which was difficult, but on, soooo immersive. If I weren't purging things I own, this would normally stay, but I don't use it much these days.
3D Connexion SpaceMouse Wireless and CadMouse Wireless – $120
For a while I was doing some CAD work in Rhino3D, and these were extremely useful. To be able to manipulate at a model using the SpaceMouse was not only really helpful, but also really enjoyable. Both have carrying cases.
3D Connexion SpaceExplorer USB – $60
This is a more all-in-one unit, as compared to the two listed above. I believe it's older, so I'm not sure about compatibility with modern operating systems, and I encourage you to look it up before buying. I'm happy to bundle it with the above units for a lower price, too.
