Oh GOD! Where to start....
Capcom CPS Changer. One of the greatest systems ever if you're a capcom fan.
PC Engine LT. Awesome handheld, how I wish I could afford the $500 price.
Zemmix, a consolized MSX Computer. Uber cool.
Me and my Virtual Boy. Ahhhh, good times....(and why I'm not allowed to have a camera when I'm bored

)
Sadly, the VB is the only one I actually own (although I do have the console version of the PC Engine LT, i.e. the Turbo Grafx 16).
