Ok, this thread is just for kicks, but let me explain the premise.
Disregarding your software collection, what is the the console that you have "leveled up" the most? I don't really mean customized—although those comments are welcome too—but accessorized to your hearts content. Basically, your ultimate setup for practical, gaming use—not just boxed systems & accessories for collecting purposes.
An example might be something like, Region-Switch Modded, Black Sega Dreamcast, Broadband Adaptor, Keyboard, with 4 Black Pads, 4 VMUs, & 2 Arcade sticks. It could definitely get crazier than that, but just list what you consider to be the console you maxed out hardware-wise.
For me, I am not completely satisfied with my Famicom Setup, but it is the one I would choose out of all my consoles.
Original White/Red/Gold Bodied Family Computer
-3D Stereo Sound Mod
-Composite Output Mod
-PPU Amp Upgrade
-SuperSlot Stabilizer
-Double Length Hardwired Controller Mod
-Famicom Disk System
That said, here are some things I would like to add to really complete the setup...
-HoneyBee NES Adaptor
-Swap slightly scuffed control pad casings with brand new replacements
-Disable the lockout chip on the Disk System
Ultimate Dream Setup...
-All of the above but starting with a brand-new, never used Famicom & Disk System. Mine are in very good condition but not mint.
-RGB Modded Famicom (while I don't like the looks nearly as much as the classic Famicom, it would be insane to own one of these that go for $400+ on Yahoo Japan)
I am also working on my Super Famicom Setup & Hope to Achieve this...
-Original Grey Super Famicom
-SNES Game Adaptor
-5 Original Nintendo SFC Gamepads
-At least 2 (max 5) Controller Extension Cords or Modified Controller Cables
-Grey Hudson Multitap
-Super Game Boy
-RGB Cable
Let's see what you guys got or are working on!
