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: 2GB of DDR3?
CPU: (Shouldn't bottleneck)
Mobo:
PSU: 600W 80+ Certified?
Card: 1x Radeon 5830 (Overclocking and Underclocking memory)
Case: A slice of wood from Home Depot
HDD: Sata2 120GB (Only $10 so...)
I don't recommend doing this, but if you do:
OS: Ubuntu works.
RAM: 1GB should do.
CPU: It won't, get the cheapest you can, usually an AMD single-core.
Mobo: The cheapest you can get.
PSU: 450W from a good brand should be enough. Consider getting 80+ Gold.
Card, case: Ok.
HDD: OK but alternatively you can use a USB flash drive.
+1 for saying what I actually wanted to say! good call on usb drive too, but i use old mobo's and they don't support usb boot so be carefull going that way. also good call on P.S.U. 600 80+ is overkill, I used a 550w 80+ on a 5870 and still only drew 320w at wall (kill-a-watt)
