Case (possible case modification): Can someone recommend me something good?
Since motherboard combo already have it's own PSU (Power adapter), I was thinking to buy this one:
APEX MI-008 Black Steel Mini-ITX Tower Computer Case 250W Power Supply - Retail http://www.newegg.com/Product/Product.aspx?Item=N82E168...
Remove the PSU from Case, and put extra fans or something like this in it's place.
Somewhere I saw someone doing similar modification, but I don't think I remember where I found it before.
For a tuner, I would highly recommend that you get a dual tuner rather than a hybrid like the one you linked. The difference is that a dual tuner can pull two broadcasts at the same time (record one show while watching another for example). A hybrid tuner can only switch between ATSC and NTSC broadcasts, but cannot record or display two broadcasts at the same time.
I personally have the A188. There are some of these cards that have a problem with disappearing. I had that issue and had to RMA for a replacement (around Nov. '09). The new card is GREAT. Just thought I would warn you because I'm not sure if the stock of defective cards has been depleted yet. I hear good things about the HVR-2250, but it is more expensive than the A188.
