Scaled flat sided images of modern computer parts for DIYing cases?

[Keystone Nyan Cat]

Are there any resources for scaled (consistently sized) computer parts? For instance, a box or so for an SFX and proportional to it ATX PSU, GTX 1080, ATX, mATX, mITX boards, etc. from the XY laying parts flat on on their sides. I plan on DIYing a case and while I can do this in Photoshop, it's tedious and was wondering if someone's already created these resources. Cheers!

Its how I do all my build planning, even now fully built my house to scale so can re arrange rooms and see if new furniture will fit. Its fantastic just takes a bit to get used to the hotkeys, but way easier than photoshop

The form factors (ATX, SFX , uATX etc) are standardized and you can easily find the specifications online (motherboard size, screw placement, io shield size etc)

 

Some of the documents you can find here: http://formfactors.org/Archive.asp

Whoops, should have clarified- I'm not looking for dimensions, but pictures. So stock photos that are propotionally sized to eachother.
