please advise on buying a new pc

[Aerodynamic]

ive noticed most companies selling full pc combos cheaper than getting it all seperately at scan..

after something with the following specs;
AMD64 3.4 or better
1024 ram
200gb hd
dvd/rw
decent graphics, thinking 6800
case shorter than 370mm
guessing i will need a 550w psu, duno if this will fit in a case shorter than 370mm :X


thanks for any help you can give :)

a few questions for you:
-what are you going to use it for?
-how well do you want it to do the tasks you demand of it?
-how much do you want to spend
-can you link to some things on the net that you've been looking at that you like or dislike

not quite sure what you mean about fitting the PSU, but an ATX one should be a standard size.

well its a new pc for my dad, he does alot of photography and just got a new slr so i guess buffering etc is important, but might also wanna play a few games on it.
case needs to be <370mm high to fit under a shelf but i duno if a 550w psu will fit in one?
lookin to pay £600ish

needs a SD card reader too
