Frugal Computing

So I was tasked with spending under $300 to create a computer worthy of playing Battlefield 2. That task wasn't that hard, especially since I have some spare parts lying around...
I had a case, a hard drive, CD-ROM drive, Windows XP Pro, and MS Office 2003 to spare. Since this computer's main focus was to create word documents and play BF2, the CD-ROM drive would suffice.
Anywho, I dug up my spare copy of Windows XP Pro (academic versions replaced my retail versions, so I reactivated a retail XP Pro) and I had a few open licenses to MS Office 2003... so I threw those in.
If I didn't have a spare license of MSOffice2003 I would have just installed OpenOffice.

Anywho, the final computer ended up being:
Athlon 64 3500+ with 1GB DDR1 RAM
Geforce 8600GT and 120GB Hard Drive/CD-ROM drive
Windows XP Pro all running on a 450watt PSU

Yea, I went with the 8600GT since after a rebate it was only $80... I was going for lowest of the low with the ability to play BF2. After putting everything together I was happy to see BF2 runs very smooth at 1280x1024. Everyone's happy with this computer. I spent about $280 in parts and that was with tax and shipping. I suppose if you didn't have a copy of Windows lying around you could tack on about $150 for a license of XP Pro... Still a pretty good frugal computer and the most important thing is that it does what it needs to do with the budget that we had to accomodate for.
I did a stress test on the Power Supply I went with and it does great. It is a 450watt that we grabbed for about $40 and although it is on the light side, the power coming out of the unit is spot on and after the two days of straight testing it still holds up.
