[Update: I have posted an article about all the computers I've owned].
Pictured below (in the final year of its existence) is the first computer I ever called my own. Built out of scrap parts my Dad brought home from his office, I managed to build the computer as a 33 Mhz 386, with 2 MB of RAM and a 20 MB hard drive, eventually upgrading it (in stages) to a 66 Mhz 486 with 8 MB of RAM and a 512 MB hard drive!
mmm... SCSI in a PC!
How, you may ask, could a diehard Mac/Apple fanboy start on a 386? Well, it was all about budget, you see. Free is good, especially when you're a little kid with absolutely zero dollars in the bank.
