If I could afford an A630 and one was up for grabs, I'd jump at the chance to get it, but alas I'm poor and A630s are rare in these parts.
I have an A1200 and a CD32 for AGA stuff
I used to have A600 with M-Tec 630-42 Turboboard (68030/42MHz) back in 1999 for Internet and stuff. It was quite useful if you use Workbench in less than 32 colors. In 32 colors the serial port was getting slow and I was not able to use the full capacity of my very fast 56Kbps Atrie modem. I still have two working modems, but no phone line anymore.
The Internet was not that colorful back then, but I remember the machine was getting hot quite often and if you type aggressively on it, you can misplace the M-Tec and I had to open it, place again the card over the 68000 CPU and close it back in the hope it won't misplace something else (For example the two 3.0 ROMs). The cool factor was the Frankenstein monster was fitted into the small case and working.
