What will you be doing with this PC? Be as specific as possible, and include specific games or programs you will be using.

Besides basic student use (currently writing my PhD) I would like to upgrade my PC for music production (Ableton Live) and some gaming (Witcher 3). At some point I would like to get myself into video editing but (not in short term).

What is your maximum budget before rebates/shipping/taxes?

The cheaper the better. Since I am hoping to reuse as much parts as possible I will say something around 350€-450€ ( I don't know if this is reallistic).

When do you plan on building/buying the PC? Note: beyond a week or two from today means any build you receive will be out of date when you want to buy.

As soon as possible.

What, exactly, do you need included in the budget? (Tower/OS/monitor/keyboard/mouse/etc)

Nothing!

Which country (and state/province) will you be purchasing the parts in? If you're in US, do you have access to a Microcenter location?

I am from Spain, Madrid.

If reusing any parts (including monitor(s)/keyboard/mouse/etc), what parts will you be reusing? Brands and models are appreciated.

I have an usb soundcard (Focusrite Scarlet 2i2), monitor, keyboard and mouse.

Will you be overclocking? If yes, are you interested in overclocking right away, or down the line? CPU and/or GPU?

I don't think so.

Are there any specific features or items you want/need in the build? (ex: SSD, large amount of storage or a RAID setup, CUDA or OpenCL support, etc)

SSD will be nice.

Do you have any specific case preferences (Size like ITX/microATX/mid-tower/full-tower, styles, colors, window or not, LED lighting, etc), or a particular color theme preference for the components?

Reusing my case.

Do you need a copy of Windows included in the budget? If you do need one included, do you have a preference?

I have a working copy of W10
