Beige proto-iMac. I had a 5200 as a teen and upgraded to either a 5300 or a 5400 at university for a few years — the latter broke while at university and I upgraded again to an eMac, but I think this was before then.
HA! I used REALbasic a bit back in the day, then spent my time comparing it to LiveCode, back then called Revolution. Geoff Perlman and I once co-presented at WWDC to compare the two tools.
Pizza box? I loved the 6100.
