A recently constructed computer with an estimated budget of $85 USD. It is to replace the even older Dell Optiplex GX1, which had been unstable since 2007. Some quirks, one sound-related, one network card-related, and one PC case-related, were quickly rectified before the transition.
2011: June. Parts were carefully picked for this build, except the computer case. It was originally going to a Gigabyte case, but looking back, in a way, I'm glad I didn't buy it, as the USB header probably would have been for a Gigabyte motherboard... which I do not have. After the parts arrived, they were tested for functionality and possible bugs before final use, especially the motherboard. Also, late July. Bought THREE Pentium III-S CPUs for nearly $9, including shipping. Testing them worked (recognized), but hanged the PC under BIOS VBD42 [it froze on the FIC screen, right before the system stats]. Upgrading to VBD43 fixed the issue. The CPUs worked: the computer recognized them and booted normally with them in use.
2012: December. Finally upgraded the CPU to a Pentium III-S CPU.
2013: November. Geforce 4 MX400 graphics card replaced with a recapped GeForce 7600 GS graphics card.That also required a replacement PSU. That replacement did trip the Windows XP activation, though.
2014:January. This build may have to be retired sometime...
