I'm a 'server' guy so my views are skewed by that. I do have some questions:
1) Are you building a new computer from the ground up or just replacing the case on your existing one?
2) What is the computer going to be used primarily for?
3) What is most important, performance, storage, or data protection?
Since I work beside my computer 10+ hours a day, I was so happy when I finally got rid of my over-clocked gaming 6-fan full tower system and replace it with a mid tower because it reduced space, saved electricity, and is SO much quieter. Over the years, the led lights got annoying so I ended up disconnecting most of them. (They ended up lighting up the rats nest of cables behind my desk which I like to keep hidden...)
I realized that I no longer needed 10 drive bays and a RAID controller so I scaled down. Now I have a single 250 GB SSD drive that only has Windows and installed programs on it. I configure everything to store its data on my first 1 TB SATA drive and have a task that runs a few times a day to sync all data to a second 1 TB SATA drive, which in turn syncs with an off-site file server. While I took a slight performance hit, I did move my page file to the second SATA drive to extend the life of my SSD drive. Additionally I have 2 NVIDIA GeForce video cards with on-board memory to drive my three monitors although sometimes I add a fourth one when needed. I do wish I had spent the extra money on a motherboard that supports SAS drives, though.
I only provided the above information as a comparison. I found the new setup was significantly less expensive than the gaming system, runs circles around it, and gave me a noticeable drop in my electric bill. It boots up in about 7 seconds and I am seldom waiting on anything even though I usually am running 20+ programs at the same time. If you are a hard core gamer and are looking for a high performance gaming system, ignore everything I just said.
Another note, this setup works well with VMWare Workstation, where I often am running a CentOS server, a Windows 2012 R2 server, and an Ubuntu server all at the same time with good performance across the board. I do have the disk image files split across the SATA drives so they don't impact my normal work from the SSD drive although the hypervisor does run from the SSD drive.
If you're just looking for looks, I'm not the guy to ask, since I like to keep my workstation clean and the tower hidden.
Hope this helps!
