The 19 strangest PC and gadget upgrades under $99 for Cyber Monday — here are the wackiest Black Friday deals you can still get

OwlTree's remote power switch is just a power switch, but it's a big, inviting button with a spiffy blue LED ring to indicate system status. It also has a nice, long 5.7-foot (174cm) cable for flexibility and comes with a header splitter so you don't have to add any extra cables to your build. Best of all, it's just $6.99.

If you'd rather not run a new wire to your PC at all, you can grab Aukuoy's wireless power switch. The receiver for this button slides into a PCIe x1 slot, so make sure you have a spare. You may also want to pick up some splitter cables if you're converting your system to wireless remote start, as this remote button doesn't include them.

A wireless button for turning your PC on/off. Big red button vibes give off danger signals. A wireless range of 80 feet over the 2.4GHz frequency.

A floating and spinning 5 Watt Bluetooth speaker that's shaped like the Death Star from Star Wars. Using magnetic levitation, the speaker is suspended in the air. Looks cool on any desk.

An RGB illuminated 2-button keyboard for copy-paste functions, or even to use in some rhythm games
