OP, I don't know what your talking about, Newegg is expensive....

A good 2GB DDR2-800 stick ranges from $33 to $35 with free S&H.

A nice 4GB kit is $63.

2GB kit is $32 to $37.

You can NOT add a video card to that PC.SDVO/ADD2 is a proprietaryinterface made by Intel which is meant to be able to add multiple monitors a PC. These multiple monitors run off of the on-board GPU.

Though according to the HP Specs, it has a PCI-E 16X slot... The case DOES support full sized video cards, so as long as they aren't longer than the PCI-E slot or just 1 to 2 inches longer, it should be okay.

You might be able to get away with longer cards with how the insides look. So a 9800 GT should fit, just try and keep it to single slot cards and not dual slot. You'll need to upgrade the power supply though.

Amazon's pre-order price for BL is $45.50

You can download the CD online from any torrent site. It's not illegal as long as you use YOUR product key and activate it legally with microsoft.

Why isn't it illegal? Because your buying the license, NOT the CD.

Comcast doesn't say anything unless you go over the bandwidth limit two months in a row. If you do it for a third month they will cancel your contract and you have to sign up for business services with them or a different ISP.

Yes, the US average is 6 Mbps...

Doesn't look like you should, you you really only need two DIMMS of 4GB total anyways which should be able to be put in the DIMM slots furthest away from the CPU.

Single card solutions are always more desirable over multi-gpu setups.

You can't view your scores offline, there aren't extra GPU benchmarks(not really needed though), there aren't four different testing presets to use, you can't change any of the display settings like resolution or AA or AF.

You don't really need that stuff, but it's nice to have. It's $20 and you can install it on PC after PC so you don't have to keep buying it.

64-Bit is becoming the norm now... Not that many problems with it really especially with Windows 7 fixing to be released here in a few weeks.
