Used to run my A1200 with Bliz1230/4 with 3.5" hd and cdrom and 3 external drives with an A500 heavy brick power supply. Then I decided to buy an Infinitiv tower at a fair in Antwerp and those guys couldn't believe that I didn't need a tower power supply and so I only bought the empty tower

I only switched over to a tower power supply a year later when I bought a Zorro4 busboard ...
