I support 10 PC's in an small office environment and have a "dead" (deemed by the Geeksquad) mobo on an Emachines T2240 with a celeron 2.2. Is replacing the mobo on this machine a good investment relative to just replacing the whole PC? I don't think it was very expensive, but it makes for a decent office machine if it will give us another 2-3 years. We don't have a huge budget so I'm trying to consider all options. If a mobo swap makes sense, any recommendations where to buy it? I see in other threads that the mobo might be a Trigem Imperial GL_VE motherboard with an i845 chipset. Replacing a mobo would be a first and I'm not a full-fledged tech or modder, but I have replaced other components in a PC's like hard drive, optical drive, power supply, PCI cards etc.and could probably pull this off. Thanks much in advance.
