I live in australia....So i dont think any of you could build it for me.lol
Australia actually has a very vibrant computer enthusiast community. You could definitely buy the parts and find one (a computer person) to build it for you. You'd have much better parts and come in at maybe 60% the price of an equivalent from a name brand.
Maybe even less.
Really, it's not complicated. I know it seems complicated. It isn't. If the wiring doesn't have to be pretty most people here can assemble a computer from scratch in under 30 minutes.
Parts only fit one way, they all slot in place with the exception of about 16 screws that are all very straightforward.
You have a case, a power supply, a motherboard, a cpu, a graphics card, memory, and a DVD and hard drive. Everything just slots into everything else except for the motherboard that screws onto a mount in the case, and the drives as well. They are then connected to the rest of the computer via very simple cables that just slot into place like the HDMI connector on your TV. Then it's just a few power cables here and there, all very obvious (this one has 8 square connectors, it goes in the hole with 8 connectors). It's almost impossible to screw up, honestly.
Another option you may have is something similar to what I have near by- it's a specialty chain called Canada Computers that only sells PC parts and they will build your system for you. You buy the parts, bring them to the build counter, give them seventy bucks, and they do a really sweet job with really nice clean wiring etc. Usually in 12 hours or less turnaround.
We're not muscle car heads (not that there's anything wrong with that) telling you to get the 8 cylinder because it's got more power and so what if it costs more-- we want to A)save you money while B)getting you better parts for that money than you'd get from an OEM. It's a fair amount of $ to make a good computer. Usually $1000 or more. Please reconsider the build it yourself option. Don't waste your money.
Also - yes applying thermal paste and an aftermarket cooler can be annoying, but you don't have to. You can start with the stock cooling that just clicks in place and everything is preapplied. You don't need to know what I'm talking about right now to be able to do this. They actually had a competition on European TV called supermodels vs nerds or something and a very... 'dim' young lady who'd never seen the innards of a computer actually managed to swap out a CPU. You can do it.
