Well after missing yesterdays might aswell put 2 up today! This one Is gonna be for those who want a media center (form factor and component wise) so it won't be suited as much for gaming.

Case: These computers are ment to fit in with the console and tend to get a bit pricey. 85$ (Review)

Motherboard Proccesor: This is a higher end Pentium D ( first generation dual core) With PCI-E x1 and x16 also 4 SATA headers and 4 DDR2 slots aswell as integrated graphics. 185$
Alternatively you could usethis, from the frys add Wed4/18
Motherboard+ Proccesor: ECS PT890T-A + Intel Core 2 Duo E6400(Nice!) $190
Included are all your standard features, 5.1 sound, ddr533 support PCI-E and Obviously this is one of the new Intel processors which are top of the line (Amd sadly has fallen behind as far as price vs. performance) they also are great overclockers!

Hard Drive: This is a well placed drive from NewEgg. Now because this is a media center computer I would recommend two of these for a combined 800GB storage capacity (HD shows can go over 5GB/ hour). 200$

Optical Drive: a basic Sony DVD drive similar color and a good brand.

Ram: 2 Gigabytes DDR2 pc2 5400 667mhz ram 99$

The case review was pretty slick, and the case accepts ATX parts (making it essentially a computer on its side) which is pretty awesome.
