Buy some short and some long.... Really mess with them !

Looks like a cpu/gpu type power connector. Even if its a standard plug does not mean its a standard pin out ! Craft computing on YouTube had what looked like a standard plug in his server but it had a 12volt and ground switched, so would have caused some real damage

I second this, when a drive shits the bed a sata controller handles it better, some times with a USB adapter you mess the whole bus up and need a reboot of the machine (from using them on windows experience)

Not sure on your location as from the picture it doesn't look like you're in the USA. However some places have restrictions on gathering water from your roof due to the materials used to clad the roof being poisonous. I would just double check that as I wouldn't want to consume any fruits or vegetables that have been grown in water that wasn't safe. I would also use a water butt or gatherer rather (totally covered from sun light) than hosing directly into a plant bed as if it's raining. The plants will already be getting watered from the rainwater so you want to store the rainwater for use later.

They also put out a huge amount of heat ! Quite useful in old high rise flats !

I suspect it completes almost instantly if you agree to it tho ?

Web hosting is free, but the extras are non-optional and cost money LOL

Nuke'em from orbit, its the only way to make sure.

Had this before for work on about 20 client PCs. Turned out there was a firmware issue with a load of disks that would peg the disk at 100% when doing nothing. It was really doing garbage collection but never ever finishes. A firmware update the drive and a windows defrag (it doesn't really do a defrag on a ssd, but they still use the same util) corrected the issue.
