Well, from what I heard the AMD 64 is similar to the Intel P4 chip, the 3200 is the processor (3.2 GHz - pretty damn quick, most likely with an 800fsb and 1MB cache), 512 ram (standard, but sufficient) ASUS mobo mean the motherboard is made by a company called ASUS (dunno much about Mobo's so no help there then

)
Dunno is 8x DVD wrting is fast or slow for DVD writers TBH, tho it's gotta be better than not having a DVD-R right? And a Mercede's case sounds like the new cases that look like C class Mercs;
I have a 15" TFT, and although I like it if your not trying to save space it's deffo worth going for a 17" (as I prefer the look of 1024 res, and it's easier to read on a 17" than it is on a 15". 15" is better for me tho as I want to save desk space in my room)
