Building home web server

[blankwire]

I'm toying with the idea of building a web server to host a website and some files. The parts I'm considering using are:

ASUS P5N-E - Free (already have one lying around)
Intel Celeron E1400 - $49.99
Gigabyte 7200GS - Free
Kingston 1GB DDR2 800 - $12.49
Antec earthwatts 380W - $39.99
Western Digital Caviar Black 640GB - $79.99

Total cost: $182.46

Edit: I also plan to use the latest version of Ubuntu Server Edition with a LAMP setup.

My ISP also has a program that allows me to up my speeds (from 15 Mbps down, 2 Mbps up, to 30 Mbps down and 5 Mbps up) and let me run a web server with a static IP address for an extra $10 a month.

My questions are:
1) Is this a good setup? Is there enough power available? I don't expect the site to get a ton of traffic.
2) Is the bandwidth enough for transferring relatively large files over the web, realistically?

Thanks for the input.

1) That PSU is more than enough for that system. The Celeron should be enough for a low-hit website. I have some reservations with that mobo since it's an old Nvidia chipset mobo (650i chipset was a bit unstable)
2) AFAIK, yes

With respect to #2, yeah. 5 Mbps translates to about 640KB/s. If these files are for the world, you may want to consider making torrents and throwing it up on The Pirate Bay. Thus, you'd have your own bandwidth and anyone who downloads it contributing to the overal download speed.

How many people will be accessing these filea? With a 5Mbps upload I would heavily consider BitTorrent for distrobution like Master Bob suggested. 5Mbps is very slow for a web file server.

Then again, if only a handful of people will be accessing it a week and the file sizes are small, it might be sufficient.
