Since we are going to need some serious components to keep up with the Pentium 4, some super fast memory and an overclocking friendly board will be needed. My usual overclocking buddies at EPoX have severely let the side down on this front for a change, with their Canterwood capable of no more than 1.6V on the V-core - pretty measly. I therefore chose the IC7 from Abit, a feature packed board capable of a nice 1.9V on the CPU. I didn't go for the IC7-G flagship version as I don’t want or need SATA raid, nor gigabit LAN.
For the memory I have some Corsair PC3200 LL Twin X, as reviewed here. It's certainly no longer the fastest dual channel stuff around at the moment, but I don't anticipate needing more than the 220Mhz it will provide (at relaxed timings).
A hefty system needs a hefty power supply, something often overlooked when your new uber-computer doesn't clock as far as you had hoped. Nonetheless this Enermax EG-651 should be more than good enough for my needs.
Rather than crack open the Asetek Vapochill, I wanted this system to be part of my Hi-Fi PC project, the case of which you can see here. I have therefore chosen the most powerful air cooler known to man, the SLK-900. However I value my sanity so the fan included is a nice quiet Papst NGM 80mm.
