Bloody hell - and i thought i was a die hard amiga fan many moons ago when i was still using mine on the net via a Miami demo and 56k modem (had to use a PC to patch it to v90 lol).
Mine was also a 1200 power tower conversion, power flyer IDE thingy, 2x hd and 2x cd , only 040@40 with FPU with 16 or 32mb, os3.5 (bought the 3.1 roms). My case also had a custom paint job (originally the power towers were beige). I tried to replicate the amiga manual square block pattern.
Sadly, the rise of the PC and the cheapness of its components spelled the end of it
sold it to someone on IRC in the end for a fraction of what it cost me. The death of CU Amiga didn't help either.
Understand now you can get FPGA dev boards that literally are 68k chips with the chipset running much faster than the originals ever did, so authentic experience with backwards compatibility, but newer and faster hardware. Never saw the point in the PPC stuff (and the blizzard boards were so expensive!). I stopped tracking the scene once it never seemed the OS would live on new hardware, and i could never get my 1200 board stable, even trying to the 1D4 board mods...
