Then i am lucky since i have 3 Amiga 2000 and 1 Amiga 4000 
Yes, very lucky. :pint: My first big-box was an A2000 I picked up some years ago, and spent a long while hunting down various expansions making it perfect for me. (The 2000 is definitely one of my favorites!) Up until that point, I had always had 500's and 1200's. I really enjoyed being able to buy cards, then plop them in the huge case without any fuss, or worry about cooling or power. My first RTG card was a CV64/3D, which was simply amazing compared to AGA.
Expanding the 1200 much beyond an accelerator and a few do-dads always felt like a complete hack-fest, not to mention the sheer terror of the clockport, and mounting challenges increasing the risk of frying something. Even the accelerator can be a pain, since most of them have the CPU facing down - I really despised having the 1200 "up on blocks" when I had the Blizz 1260 in there, simply ridiculous when you can't close the trapdoor and call it good.
