Well, it’s been a couple of months in and, I’ve been loving it!
The Optiplex 7010 didn’t last long, and this was soon replaced with the newer Optiplex 5030 SFF. This model is a nice upgraded due to the nvme and the Intel processor. So, the current system is; I5 6500, 16GB ram, 128GB nvme. This is more than enough power for what I use. The actual machine was only £49 ($60 roughly), and was an ex-business machine that was being sold off in a job lot.
Rock was installed within minutes and I pointed the core to my library and I was back up and running in 10 minutes over all. It’s now hidden out the way in the porch so I cannot hear it or see it. Bliss.
