My custom PC I built sometime in 2004.
CPU: Athlon64 3200+
Mobo: Asus A8V Deluxe with practically everything integrated busted while still being able to boot (well, eventually... usually after a few hours of trying - after which I never turn my PC off until it crashes again or such)
Case: Antec Sonata Piano Black
PSU: Nexus NX4090 400W (2 PSUs have blown up so far, hoping this one lasts until I can build my next setup)
GPU: Gainward GeForce 6800 GT Ultra/2400 Golden Sample Goes Like Hell 256MB (I just LOVE that name)
RAM: 2GB DDR400 (4x512MB, Dual Channel)
HDD: 2x 250GB, 4x 300GB, 2x 500GB, 2,7TB total
Monitor: BenQ G2400W 24" black
DVD: Lite-On SOHW-1633S that won't read or write CDs anymore, only DVDs.
Keyboard: Microsoft Wireless Desktop Elite Keyboard
Mouse: Microsoft/Razer Habu (R.I.P. Copperhead)
Headphones: Sennheiser HD 570
Speakers: 2x Behringer Truth 2031A
My setup is getting pretty old already but since I haven't played much after quiting WoW ages ago the only real problems are the failing mobo, integrated sound which blows and the fact I can
almost watch 1080p video without stuttering. Currently trying to save for a new mobo/CPU/RAM/GPU/PSU/case... and more hard drives... and a GOOD sound card... and a subwoofer... and a wired keyboard, maybe G15... and eventually a bluray drive... *sigh*
Good setup, should last me for the next 5 years atleast. Or until I get bored and build something new.
Sounds quite optimistic. 5 years is freaking forever in IT. My last PC was high-end in 1998 and a piece of junk in 2004 and I had replaced everything except the mobo so it had rougly 4x the original computing power and RAM and the GPU was infinitely faster than the original

. My current setup was also high mid-end when I got it and now it's just meh.
