The PB computer I had(this was in the USA in the 90s, I don't know if they still do the same crap) had most of the parts integrated into the motherboard, so upgrading anything but the processor, 4 PCI devices, the drives, and the memory was nearly impossible(graphics card was integrated which was the thing that pissed me off later). To make it worse, the on board clock(not the instructions clock, but the one that was keeping time in the BIOS correct) was a Large Capacitor and not an actual battery, it died out and the BIOS would not allow me to access the Operating System. If Packard Bell still does shit like this I will not buy their computers...
