Request: Convince Me I'm Wrong and Should Just Get an iMac

Hey /r/hackintosh

Currently on a MacBook Pro Retina 2013, and now out of AppleCare warranty. Saw the new 2017 iMacs and started to think seriously about them as a next work machine. Then saw the 21.5 4K specs, and price tag for RAM upgrades and stumbled on Hackintosh builds.

My request: counter-balance my buzz and convince me I'm wrong to try it, and I'd be better off with a 'just works' out of the box something. I use my MBP for business: office apps, web browsing, light Photoshop and basic video recording/editing (no Final Cut Pro yet, only Quicktime and iMovie).

I've tinkered a bit with internals before (replaced an LCD screen in my a 2006 MacBook, replaced an HDD with an SSD in a 2010 MacBook Unibody), but am otherwise totally green to self-builds.

The appeal of a Hackintosh would be significantly more RAM, slightly larger HD, and perhaps slightly faster video processing speed than my current machine (8GB RAM, 256GB SSD), but with otherwise comparable specs, and a good bit less expensive than a new iMac.

Imagined build components would be something like this:

Hackintosh vs iMac

That aside, I'd like to keep things functioning essentially as is.

So please, tell me why this might be a bad idea. Why the components are not ideal, or that I risk insurmountable technical difficulties, or that it's not worth messing with a CustoMac when it comes to business machines that I need to rely on, etc.

Thanks in advance for any help slowing my roll here.
