Building a powerful yet low cost desktop with OS

Building a desk top is not as hard it would sound. You just need the right parts.
I built a system using a low cost ATX computer case with a 450watt power supply.
Then I Bought:

1.ABIT GD8 mother broad
2.Geforce 6200TC made by eVGA
3.Intel 2.66GHz Celeron D CPU BX80547RE2667C
4.512MB (2 x 256MB) 184-Pin DDR SDRAM Unbuffered DDR2 400 (PC2 3200) Dual Channel Kit
5.5618PSV 56K PCI Modem. Made by Archtek
6.Seagate Barracuda 7200.7 ST340014A-RK 40GB 7200 RPM 2MB Cache IDE Ultra ATA100 Hard Drive

I tested my configuration with Red Hat Linux, Mandrake Linux, Xandros Linux, Linspire,Ubuntu, and Slackware.They all worked just fine. Note: all other linux distributions should work as well. I just have not had a chance to test them all.

The only thing left to buy if you dont all ready have them is:

1.Keyborad and mouse

2.Computer Monitor.

3.Speakers.

4.CD/DVD rewriter.

5.Floppy Drive.
