Started work on sorting out the server today. Odd place to start, but I looked at the keyboard as it was utterly filthy and the key action felt almost gritty. It is an antique PS/2 Acer mechanical from roughly 20 years ago. Having pulled all the keycaps off, I found the extent of the dirt. Most, if not all of it originates from the loft where the keyboard has spent the last decade. Incredibly, it still worked perfectly.
Having washed all of the keycaps and cleaned the body of the keyboard. I have also cleaned all of the switches, washed them off then applied some anti-corrosion lubricant. (Kontakt 60, WL then 61) The switches felt massively better.
No idea who made the switches as they are branded as acer. They feel similar to a cherry MX brown/blue.
Finished. Sadly the yellowing of the keycaps couldn't be removed.
On to the case swap. The 750D is quite a bit bigger than the CM690. I put a new 8TB drive in already as that is going to be used as an rsync disk for certain files from the main array.
Deconstructing the 690 was simple enough but the last 6 years in the loft haven't been kind. That green cloth was clean to start. All of the fans and filters are caked in a fine black dust.
The add in cards out. I really should upgrade the RAID controller as it's the oldest item but I can't be bothered finding a replacement.
All the drives now transferred across. Just the PSU and motherboard and fans to put in.
