Noise is a big issue since the rig sits at table top level to my immediate left, right next to my file server, and both are wedged into a corner. There's a LOT of reflected sound from the rear exhaust fans that bounces off the wall behind them. I deaded some of that by putting up cork board on the wall behind them.
Difference of night and day. I can barely hear the new rig at all - most of the noise is from the server which is fairly quiet but not as quiet as the new rig. At least I can carry on a conversation with someone outside the room now.

- AMD XP2400+ Retail (Retail HSF which is VERY quiet BTW) - Not planning to overclock.
- Epox 8rDA+ mobo (no whining chipset fan!)
- 512Mb (2 sticks of PC2400 DDR) - going to replace it with 2 sticks of 512Mb PC2700 and run the ram clock at 166Mhz eventually
- 160 Gb Maxtor HDD (nice quiet drive)
- Geforce4 T4800SE
- Antec True430 PSU (VERY quiet PSU!)
- Sony DRU500AX DVD-RW
- Lite-on 52X CD-RW
- Bronze Antec SLK3700AMB case (darn nice case)
- Front-X front panel audio/gameport panel
- Kingwin aluminum ATA133 removable drive tray with cooling fan (makes it easy to connect a client's HDD when I need to Ghost it).
Nice to finally have a case with front USB ports too.
