Hey guys I am going to be building my own custom computer very soon and before I buy everything I just want to make sure I dont need to think about buying anything else just now and that everything will work together nicely. Because I dont want to buy it all and regret it later

The Case!

The HDD!

The Motherboard!

The PSU!

The GFX Card!

The RAM!

The Processor!

Just some Thermal compound for the processor
Static mat so I dont damage my parts

Any replies will be very much appreciated!

I don't see:

DVD drive
OS license (Note, in most cases, you cannot use a Windows license that was purchased for, or came with another computer).
Keyboard
Mouse
Monitor
Speakers

Also, I always recommend using a good UPS with AVR on all computers.
