I couldn't believe I was actually able to find an image almost exactly like the IBM XT clone my dad bought my brother and I in 1987! This is it right down to the key lock and yellow and red buttons, but ours had two 5.25" floppy drives. But get this...
1987 - PC XT clone with two 5.35" floppy drives, 640KB RAM, Hercules graphics card and amber monochrome monitor, running MS-DOS 3.0
1989 - I work my ass at the local community college of during the summer in the computer lab so I can afford to upgrade to a VGA card and 15" monitor.
1990 - I upgrade the processor to 10Mhz and fill the DIP sockets to max out the memory to 1024KB.
1991 - I get a part time job at CompUSA and buy a Epson combo drive - 5.25" and 3.5" in one bay!
1992 - I buy a 486DX2-66, CompUSA brand motherboard and case. The combo drive and VGA card all go in the new case.
1993 - I take the plunge and get my first hard drive, 80MB.
Now I lose track of the upgrades as they became more frequent. Hard drives were a very common upgrade since I started doing video editing early on. Video cards, too. I think I've gone through six montherboards. But the kicker is that this computer that my dad bought is the direct progenitor to the CustoMac sitting in my living room! Upgraded piece by piece and slowly evolved into...
2016 - CustoMac, i5-3570K, 16GB RAM, 4TB Hard Drive, Intel HD 4000 Graphics, Full HD monitor, running dual boot Windows 10 and just finished upgrading to El Capitan yesterday.
