My opinion is that users with heavy CPU or memory requirements are still better off with a desktop system unless portability and battery-powered usage are essential. A laptop is still a compromise for these use cases.
True, but laptops are pretty much at the point where they can handle the biggest music projects. The multi-core score of the MacBook Pro 2016 is about half of the desktop I have (which has so much power that I never reach its limits). I'm gradually breaking free from being stuck in one place though, and my fully-upgraded, beastly Classic Mac Pro desktop (30 KILOS) feels very limiting since its massive size and weight confines me to working only in my own studio.
I've bought two Dell workstation/ server towers (T3600 & T110 II) for < $1000 in the last couple years (Xeon E5 6-core & E3 4-core), and fitted these with the maximum RAM (64GB & 32GB) and multiple SSDs. Probably cost me about US$1500-1800 to get machines with far more performance, RAM & storage than is possible in nearly any laptop computer, and much more expansion capability and thermal overhead. These things will sit at their turbo-boost speeds for hours.
You bring up a good point. True workstations with Xeons are out there and when they get thrown out by corporations (that no longer need them, and want something more power-efficient to save electricity bills, and something faster), they can go for extremely cheap. I've seen $300 being asked for $6000 machines. The corporations don't care about 2nd hand value. They just dump them out for bargain prices.
That might be a really good idea for a Hackintosh project.
You can get small form-factor desktops with slightly slower processors that are at least semi-portable and if you are already carrying other audio equipment (mixing desks, outboard gear, mic-stands etc), a small-ish computer really doesn't make much difference.
True. Not sure if you saw my conclusion post?

I reached the conclusion that I'll try to wait for a 24+ GB RAM MacBook Pro which should be out in 2-3 years, and that I may even wait up to 5 years for the next generation of touchscreen MacBook Pros that Jonathan Ive
admitted to working on. But if I get tired of waiting (which is likely), I'll be building a small form-factor desktop just like you said. I could get a fast and modern mini-motherboard, a small case, a top-end Core i7 processor, and the result would be about 2x as fast as the new MacBook Pro. If I can find a case with nice shape for carrying, it'd be pretty damn good. But the best would of course be a laptop, since that has the screen included.
If you already have rack-mounted gear in 19" racks, then just buy a 1U blade server (up to 44 cores with dual Xeon E5s), and you'll have a ton of processing power!
Yikes that's crazy. That many cores aren't needed for music. :-D And a 1U wouldn't fit graphics cards. Besides, I've gotten rid of all my rack mounted external gear (tens of thousands of dollars worth of music equipment) because the digital plugins these days sound equally good now. It was a bold move but the digital emulations (plugins replicating hardware sounds) these days are just too spot-on and sound exactly like the analog hardware they reproduce, so there was no point anymore.
Thanks for your tips. I'll definitely look into de-commissioned Xeon servers. They could be a great way to get a superb workstation Hackintosh for next to nothing. I'd have to watch out for getting stuck with an un-upgradeable Xeon motherboard though. And I'd have to put it all in a compact case. But at the prices you can find those old servers for, I can't complain about the idea. Worth pursuing.
All I know for sure is that I badly want to sell my classic Mac Pro tower and replace it with something more portable. It's too damn big and heavy.
[doublepost=1478482142][/doublepost]Update: See this is what I was saying about corporations dumping old servers for dirt-cheap:
http://www.ebay.com/bhp/used-servers ... Most of that is equipment that was originally in the $3000-15000 range, being sold for $300 a box. You'd just have to look very carefully to find one with Hackintosh-compatible components and a good case. Some motherboards and CPUs may not be able to boot macOS at all. Most rack-mounted servers don't have PCIe slots, so most won't allow you to insert any new graphics card, which means that you have to look at the desktop tower-based servers to get PCIe slots (click "Refine Results" at the top and choose desktop form factor to find the actual workstations). And also watch out for the fact that some of them have very old, power-inefficient CPUs, so be sure to get the most modern ones you can find (Google the CPU names and check when they were released), if someone else is thinking of doing this. It is also very important to type the name of the CPU into GeekBench to see what the performance is like:
https://browser.primatelabs.com. This is a path I haven't gone down, but I bet it can be done if you find a very compatible motherboard, without too many CPU sockets. Then it'll probably be supported by the macOS kernel and will be possible to get it to run. A quick Googling shows that people have managed to do it. But it definitely requires a lot of research that I'm only gonna waste time on if I ever decide to go down this path. Used Xeon servers would definitely be the cheapest power-workstations ever.
