if you're doing CAD then my advice is go high-end on everything that counts. I have plenty of CAD experience from before went into IT full time, and I still spec CAD systems and support them.
processor must be Intel, any of the high-end P4s are fine. dual-processor is even better. edit - don't be tempted down the false path of the Athlon 64s, despite their siren promises of undreamt-of power. most CAD software is written on largely Intel-hardware machines, and is often sensitive to cross-platfrom changes. It's looking for Intel instruction sets and is finding AMDs. Intels are much better number crunchers than AMDs, and that's what CAD software is; number-crunching. So the Athlon 64 is a non-starter for you, trust me on this.
mobo must be Intel-chipset, but doesnt have to be an Intel branded board. Go for the dollowing makes, Abit, Intel, MSi, Gigabyte - don't bother with anything else
memory, lots of it and fast too, Corsair performs well and is reliable. get DDR400 if your motherboard will take it
hdd - go SATA you need the fast disk access for paging, and you'll find CAD needs a lot of storage
graphics, always a point of debate for CAD. unf it doesnt sit well with gaming
excellent gaming/general adaptors like the Nividia FX and ATi Radeon simply don't perform well with stuff like AutoCad and the like, or a lot of high-end graphic design work. it does very much depend on the apps. true CAD users usually insist on pro stuff like Pure or WildCAT, 3D rendering cards. A lot go with Matrox for colour reproduction and clarity of vector graphics. But the former oyu prob wont play any games on much cos they won't let you, the latter can behave q badly with some games. tbh unless you know you're going to need dedicated features, one of the high-end Nvidias is prob best for you if you're going to mix gaming and CAD. if it was just gaming I'd say the Radeons.
sound is entirely up to you. if you just want general sound for multimedia, then you may as well go with the onboard. however if your CAD work needs sound reproduction the go for a Soundblaster Audigy 2.
obv DVD-RW
I recommend a backup device, like a tape drive or a large capacity Zip or Jaz. if this CAD stuff is professional or otherwise important, then you need to securely store it and archive it.
UPS to protect you if you're in the middle of something and the power goes.
CAD work? always go with a CRT monitor, LCD do not have the definition yet. I recommend Iiyama (superb monitors) or Mitsubishi, Sony if you want to save a bit of wodge cos Mitsubishis are expensive; otherwise Belinea, AOC, and Samsung are good alternatives, a lot cheaper and no where near as crisp, but better than most others. and don't get monitors with speakers, the coils distort the image!
don't arse about with silly cases, just get a nice big one with lots of cooling. get a nice powerful heatsink fan unit and chuck loads of case fans in.
oh I agree btw, XP Pro, not Home. if you're interested there are some excellent CAD applications for Linux, it's the sort of application that works really well on Linux because the memory usage is such more efficient than Microsoft, leaving more system resource for the application to use.
alternatively you could get a Mac
