I can't offer any help on the "where" as I'm located in the US.
What type of ddr ram to buy n where?
A: Kingston Hyper-X, Corsair XMS or something else similar, reliable with a CAS=2. dual-channel recommended ... 512MB x 2 rather than 1GB x 1
Where to by a descent case, fancy one with the temp displayed?
A: The Aspire X-Dreamer is a nice case with temp display. They run about $50 USD
What fans will I need n where to buy?
A: Fan airflow is more important than sheer number of fans - quality over quantity. Panaflo makes nice fans. Antec makes quality fans as well.
Advice on graphics card dont want to spend too much on it though?
A: #1 choice would be an Asus 9800XT but they go for a bit over $400 USD. An Asus 9600XT goes for about $185 USD. I like those b/c they offer temp monitoring and are great overclockers. Any 9800 Pro card would be ok also but try to stick with a known brand. Sapphires are cheap and known to be amongst the best of the "budget brands."
What type of h/d to buy and where?
A: I have always preferred Maxtor for my experience with them - very reliable. Some people prefer WD, Seagate, etc. Up to you. 7200 RPM w/ 8MB cache is the standard now. 120GB at least I'd say. Personally, I'd like to have at least 500GB.
What dvd rom drive to buy, want to be able to read all forms of protection with it if poss ie safedisk etc?
A: DVD-ROMs are not known for being good with SafeDisc, etc. Last I checked, only the new Plexy CD-R could properly do SD but perhaps by now other CD drives can as well. Really not necessary though anyway as no-cd, erm, "assistance" is readily available on the net. If you simply want a good DVD-ROm for reading your DVDs, LG makes great ones. A lot of people like Lite-On but they're too damn loud for my tastes. They do tend to read it all though.
What processor to get, and where, need a fast reliable 1?
A: You will never get a good answer on this one. lol I prefer Pentium, Celeron, AMD, in that order. I'm running a P4 2.8GHz atm and couldn't be happier but some prefer AMD chips. Honestly, both are reliable. Look for price/performance ratio.
How many fans will I need in the case as I will be knocking out alot of dvd's?
A: Again, fan airflow is more important than sheer number of fans - quality over quantity. That said though, I have every fan slot in my PC loaded. lol 7 case fans, 1 HDD fan and 2 fans built into the PSU.
would u reccomend one where u can vary the speed of the fan?
A: Up to you. This feature is really just so that you can get some peace and quiet from the roar of your new beast. W/o it, they will simply always operate at full speed.
