That is a Cadillac and there are a lot of ways to reduce the cost without significantly affecting basic performance.
Case – you can get a good steel case for about $100 – savings $130
There are a lot of steel cases that will provide good airflow and relatively silent operation for less. The one above is aluminum. In addition, cases are also a matter of style.
Power Supply – this is the modular PSU – you only put inside the cables you need and don’t have extras stuck in there. You can get its non-modular brother for about $60 less. Also note that it is sized to support two graphics cards. If you are sure you will never want those, the PSU could be dropped down to about 500w with additional savings. I just hate to put a smaller on in a system of this caliber. As it is - if you ever want another video card - you can just insert it.
Video card – this card is midrange. If you really don’t think you want to game, you can get a serviceable card for about $100 less.
Sound card – the motherboard provides on-board 8 channel audio and is all that most use. But you mentioned it so I included it. You could go without and save $60 – maybe try the on-onboard first to see if you really need more and add it later.
Hard drives – I included a fast solid state drive for the operating system and applications. Don’t know if you know about them – they are good but expensive. You could do without it entirely and just use the other drive – at 1 TB it should take you awhile to fill it. Note that this is the one change that would affect basic performance. Potential savings $299
Optical drives – included a Blu-Ray reader. Don’t know if you need it. Can eliminate it and save $98. Of for about $100 more instead get a Blu-Ray reader and writer.
Total potential savings - $747. Net after savings - $1308.
I tried to give you a starting point – something to work from.
What is your pleasure?
