Getting up to speed on modern PC construction

Getting up to speed on modern PC construction

The last time I built a PC the tricky parts were knowing the difference between ISA, VLB, and PCI cards; juggling IRQs; and getting IDE master/slave right. Now I'm helping my stepson build a gaming PC and I've realised that PC internals have changed a lot since then. Multiple fans, thermal paste, dual-channel RAM configurations, a bizarre array of power supply connectors - it's a different world.
