Advice on (re)building a high-end Ubuntu System

I need advice. About a year ago I put together a rack-mounted developer's system with these goodies:
Mobo: Asus P9X79
CPU: Intel(R) Core(TM) i7-3820 CPU @ 3.60GHz x 4 physical cores
RAM: DDR3 Synchronous 1600 MHz (0.6 ns) 8 GBx4 (32 GB total)
SSDs: 1-120 GB SATA 3 + 1-240 GB SATA 3
HDDs: 2-1 TB Hitachi SATA 2 (7500 RPM) (source, backup and music)
OS: Ubuntu 12.04 LTS 64-bit
I put / on the slower SSD in a 40 GB partition; /home is there too, but on its separate 80 GB partition, which is now full without touching the 240 GB drive -- but a big job is coming and I'm going to need it really soon.
The question: I now want to redo this box with Ubuntu 14.04, but the right way, optimally. So: would it make sense to put the new OS on the (reformatted) smaller SSD, and keep my /home on the same drive, or is there a better way? Can I somehow mount the 240 GB SSD in /home, to increase capacity without the hair-pullers of running with LVM or RAID? I'm far from a n00b, but no guru's guru either. I really want (and need, I think) the freedom of having a larger home. Reducing the present OS partition size to 20 GB would provide a total of 340 GB between the 2 high-speed SSDs for the /home of my dreams. Can this be done as I've described? Hopefully some *nix guru can answer, because I'm at the end of the runway with this one. Thanks!

First of all, LVM is not complicated. It makes expanding and reducing disk sizes stupid simple, especially adding drives and capacity. You should use LVM.

It's complicated (OK, painful) if a drive fails because that knocks out the whole chain. I've had this happen and know wherof I speak. I really don't want to chance such things as a consultant. My day-job company does, but they have deep pockets and lots of support guys on staff. Isn't there just a simple way to mount the 240 GB drive under an existing /home? This would seem to solve all my problems ... if I knew how to do do it right!
