MythDora Box Hardware

i am looking into building a fedora Core 6 with Mythtv box. it will be my backend for 3 other pcs and also a frontend for an office.
It will also be an fps mail and media server
i plan to also do some gaming on it
i have already planned on throwing in 3 Happauge 150 cards as far as the rest of the hardware goes im looking for suggestion.

PS i would like to keep it under 1300

Also to add I would like to have a 1TB of storage and 250 for os and software.

i am unsure if i should build a nas box or just add the 1 TB to this build. As i said anny suggestions would be greatly appreciated.

Is the $1300 budget to buy everything?

So you want 1 250GB HD and 2 500 GB HDs, a DVD-rom/burner, a tower case and decent sized PSU. A NAS and Server won't take much for a CPU, I would probably get 2 gigs of RAM and a video card, you say you want to game but at what level? WOW, higher or lower. On board sound, dual gigabyte net to save slots. You might also want to look at a dual tuner card to save slots and money. Why Myth? It is a PITA to set up, frre is one things but...

What size monitor are you looking at for the office front end, your games won't take much to power, a big monitor might.

I understand on the tuner cards and Myth, you know what it takes and I did hear about some work with the Fedora crew to smooth out the installs.

You need a MB with 3 PCI and a PCI-E, 3 sata ports and a IDE port. Any other needs, or parts you want to use?

For your uses, I might look at the low-end AMD with those new prices, $73 for a CPU.
