I know you wouldn't get it from here, but connecting to the internet is as simple as something like this.I use it myself, and even in my little remote corner of my house, I can do everything on the net just fine. Of course you'll need a router to connect to, but I am assuming you already have that. Another, slightly more expensive alternative is what you were suggesting (connecting a wireless adapter to a PCI slot) which you hook right into the motherboard. I have had rigs with both, and both work equally well, it's just using the USB generally costs a tiny bit less, and you won't have to run the risk of your GPU being too big and your wireless connector getting in the way of it. As far as driver installation is concerned, install your OS of course, and then install whatever you feel you need to. It really doesn't matter in what order I don't think. hitman6actual

Heres an example of one with a window:

Its got the big red blue 120mm fan on the front that put me off but i didn't notice that there is also an 80mm fan on the rear too. There is also it in red or a tri-color one!

EDIT: Other Cases:

Don't worry about the case its one thing I go cheap on my self ;). As long as everything fits and it has at least one fan pulling in cold air it will do fine... everything else is just a luxury, although I do want a new case one with a side window so people can look in and go ooh!Too_tight_shoes

They got a few of them cheap on ebuyer, the only thing that put me off was the fan on the front had an LED in it. Not too much of a problem for some but personally i didnt like it. Otherwise it was pretty nice and like £18.99. One final question is that i need to connect to internet wirelessly so how do i do that from a desktop pc? is there some extra hardware i'll need or some time of usb dongle?

I would go with the 450w psu you posted seeing as its 80% efficient and will run everything listed just fine, its also used and rebranded by a number of hardware sites as their own and is used for budget gaming setups it will do fine and is far more efficient and reliable than what you posted earlier... which I would only use for work PC's with excessive amounts of hard drives and optical drives. Also don't worry about the unbuffered ram part I don't even know why its put up seeing as buffered ram is used for servers.Too_tight_shoes

Great Thanks again! Just a few weeks and then i can enjoy building it, ive selected a case for £20... i know it seems i hav gone cheapo again but i liked the nice added feature that it has 2 x 80mm side fans. 1 runs constantly but after the temperature reaches a certain height the other fan will kick it to cool it back down again. This seemed a nice power saver, meaning im not going to be running a fan that i dont need but when i do need it it'll start up.

Well i am pretty much broke right now so nit picking to save cash is a habit i have fallen into, There is a 450w psu here:

http://www.ebuyer.com/product/151287

It says it has short circuit protection and over voltage protection which is probably a good thing to have so that the other components arent fried, although i really have no idea what im looking for in terms of connectors and the pins i need.

I saw a Corsair 4gb DDR3 1333mhz for £75.03 which seems to fit your guidelines perfectly.

It says something about it being 'unbuffered' whatever the hell that means, maybe you can explain.

One reveiw for it says this though:

'...but one thing that could be misleading is that I thought these come with a heat sink but on arrival I was horrified to see that what appears to be a heat sink in the pictures is actually a LONG WHITE STICKER stuck on the memory modules,' Is this a problem or not?

I'll total the results now and hoping i can get some extra hours for the next few weeks i should be able to afford it. Also a huge thanks to both you and hitman as your advice and wisdom has been invaluable!

This is now what i am looking at:

CPU - AMD Athlon II X4 620 £70.49

GPU – ATI Radeon HD 4850 £70.49

Motherboard - Asus AMD 760G AM3 £47.83

HDD - Samsung Spinpoint F3 £31.99

Optical Drive - LG GH22NS50 £16.80

PSU – Casecom 500w ATX £16.98

OS - Windows 7 Home Premium 64-bit £84.99

Which will bring me to a grand total of £339.57, all that is needed now is ram. I am completely lost when looking at that so advice is yet again needed.

I would still go with a 4XXX series card, because you can get much better performance for less. Your PSU is way overpowered. A 400W one will do fine. I think pretty much everything else looks fine, and if your unsure how to put things together, I would look at this forum post.Everything you need to know is right there in that post. If you use that guide, just follow it very precisely, and everything should work out fine. hitman6actual
