Critique of a future possible Sleekness? (looking at a new computer)

As for the integrated graphics ... depends on how much of the RAM it can use. Argon is correct about the cheapness of graphics cards, most of which have DDR3 memory: faster = better (probably?)
Integrated graphics suck because they share ram with the system memory, it doesn't matter how much ram you can set the graphics chip to use. By running graphics and cpu memory (it's actually called primary memory; hard drives and other media are called secondary memory) on the same bus (wire pathways on your motherboard between devices) you're actually slowing down both. As for DDR3, that's part of it, but it has more to do with the location relative to the graphics chip (closer = better; the path for integrated is longer and there's other traffic).

Remember that (theoretically) Vista 64 bit can access more than 4GB of RAM ... can more memory be added to that motherboard?
64-bit can access 16.8 million terabytes of ram (2^64 reserved addresses. 32-bit is 2^32 which is why they can't access anything past 4 GB, because there are no more reserved addresses left), it's not possible to reach that number now just because ram modules that size don't exist. 64-bit computers with 16 GB of ram exist and can be bought/built currently (Dell?). If you're wondering why your 32-bit system sees slightly under 4 GB it's because some of those reserved addresses are used to identify devices on the computer (keyboard, bios, sound card, etc.)
If you ever want to reuse an old hard drive you can find enclosures for around $25-$50 that basically turn them into usb drives. Here are some examples:
http://www.newegg.com/Product/Product.aspx?Item=N82E16817155015 (for SATA drives)
http://www.newegg.com/Product/Product.aspx?Item=N82E16817716029 (for older IDE drives)
EDIT: The SATA one mentions eSATA, for anyone curious it's just a special SATA cable with a plate that connects to the motherboard:

http://www.newegg.com/Product/Product.aspx?Item=N82E16812189150
Its as fast as if the drive were internal, usb2 is slower.
Or you can find a 1 TB hard drive on NewEgg for like $100

Heh, I remember taking up my Google cudgel and thrashing that truth out of teh interwebs after I doubled up my 2GB and wondered where some of the extra had gone.

Can anyone explain why my x64 does this?

32-bit is 2^32 which is why they can't access anything past 4 GB, because there are no more reserved addresses left
2^32 = 4,294,967,296 = ~4GB
Calculator, anyone? ::)
