OK. Been quietly plugging away when I feel like it. Got to a point where there really isn't anything else I can do.
After doing a lot of research it seems that the cloud software needs Linux. Either through Linux or a VM, no matter what. It does not function under Windows on its own.
I would have gone down the Linux rabbit hole (and will) but sadly it seems the 7300 GT is dead. What I mean is it works in Windows with no driver loaded, but if you go into Linux it installs a driver (which Windows doesn't have) and is garbled really badly. Due to this I can not work on it. Mostly because I am using a 7" screen. Maybe if I had it plugged into a better monitor or my TV I could get around that, but I really don't see the point in struggling for the sake of it.
As such I decided to focus my energy on other things. Like sorting out the PSU. I don't need many SATA connectors (maybe four?) but as of right now they were on Molex to SATA runs. Which are a real pain to plug in, and mean you need two lots of cable to do one task. Also, I decided to basically not use any extensions as they are not needed and the case doesn't have a hidey hole for left over wire.
Thankfully this PSU came with a set of connectors and a whole buttload of pins. You could basically get your own wire and remake every thing it uses. As such I removed the Molex ends from the SATA cables, and changed those to PSU connectors. I also found a Molex run (I didn't have any and was using red ones I made) which had a floppy connector on the end. I removed that and added a 5th Molex, which should be enough to power everything (the back planes use molex, so that's three). Any way, like I said I also decided to ditch the silver and red cables. So yesterday I got to that.
When I was done I was left with this.
Which is much, much better. The only other black braided cable other than the two SATA runs is the 4 pin (board needs 8+4) which I also had to make because the PSU only comes with 8 pin connectors and they don't split.
Am currently working to obtain a new fan for the PSU. It's cheap, flimsy and noisy and has developed a rattle. Am trying to get a Noctua, but it has to be a 3 pin so I have had to bid on a couple. If that falls through I will go with something else.
