I'm looking at building a single-card rig with a Sapphire 5830.
I have no plans on expanding this rig.
I need some pointers on what hardware to get.
Here's my current list:
OS: Ubuntu
RAM: 1GB of DDR*
CPU: Some sort of single-core AMD chip
Mobo:

PSU: CORSAIR 450W 80+
Card: 1x Radeon 5830 (Overclocking and Underclocking memory)
Case: A slice of wood from Home Depot
-Slapping on a HDD, mobo, and PSU won't do the job
-Gotta find out how to secure parts onto wood...use pen to mark holes and power drill into wood?
HDD: Sata2 120GB (Only $10 so...)
