The Second Portable Athlon (1/10)

The original Portable Athlon was signalling its retirement. The highly overclocked GeForce2 MX in the system finally failed, probably due to extensive operation under the cramped environment. The card seemed fine at first, but it invoked hard drive errors during booting (I thought the hard disk had gone bad at first). I think it was sending unstable signals and risking the stability of the system. Also, the case design had very limited expandability, with no PCI extension cards installable, and without a room for a floppy drive or a CD-ROM drive. I was sort of getting annoyed by that. I decided to get over this, and started building a new version. I'll show the journey around with lots pictures.

This is the EPoX EP-8K3A mainboard with KT333 chipset, supporting PC2700 (166MHz operation, 333MHz effective speed) DDR-SDRAM and 166MHz FSB. You can clearly see the markings on the surface. Like the original Portable Athlon, this mainboard is full ATX, not the smaller microATX that is commonly used in small form-factor or slim-size computers. Back in the original, though, there wasn't much benefit of using a full ATX mainboard in terms of expansion because it was blocked by the power supply sitting all over it. Not this time; those PCI slots would have real use. Here, I'm removing the default northbridge heatsink.

The default heatsink would be more useful somewhere else. I'm going to replace it with Zalman Tech's beautifully gold-coloured ZM-NB32J northbridge heatsink.

The new heatsink is now in place. Next step is to install a CPU cooler. I am to install CNPS5100-Cu, again from Zalman, which does not use clips, but four supporting bolts. Therefore, I needed to put the studs on first.

It's already been more than a month since a new system had taken place of the Portable Athlon. It was replaced by none other than its descendant, XPPort-II, a.k.a. Portable Athlon II. I still have some improvements planned for the machine, but I decided t

Escape from the Low-End The single most annoying thing that bothered me in designing the series of Portable Athlons (First & Second) is that I could not use a full-height video card. This is because the system's internal dimensions

Heat problems have plagued the XPPort-II (a.k.a. Portable Athlon II) due to the high-performance components that make up the system, while having too cramped a space to have sufficient cooling applied. The solution was to use heatpipes to move the heat to
