Can I Power 3.5" external hard disks that require a 12v wall wart, with a 12v output from a cheapo PC PSU? I also plan to use the 5v lanes to power some USB 3 Hubs (that support external power)

I would recommend MESH WiFi only if you can afford the high price, because the features don't justice the premium. For the normal users the difference between MESH WiFi and normal WiFi routers is that you have a single WiFi network as opposed to seperate WiFi network for each router in different parts of the house. I recommend a WiFi repeater, they are cheap and help to extend you WiFi coverage. Go for MESH WiFi Only if you plan to upgrade your entire WiFi setup and not just to have a better coverage in one of your rooms.

Hello, I have several external HDDs ranging from 1 TB to 4 TB that are rarely used these days because of this size and the dreaded WALL WART! So anyway I plan to setup a raspberry pi as my Torrentbox and I plan to use one of these brick HDDs. The issue is that my area has frequent power cuts everyday (random times) for 15-30mins each time. My APC 500WATT UPS is on its last string and I loathe spending too much money on these projects, so I was planning to DIY a UPS with 18650 batteries (salvaged from my old laptop batteries and power banks) and a boost converter. I plan to use the idea from this YouTube video: Is this feasible to power a 3.5" external HDD for 24x7 operation. Note: I plan to boost the project with 6*18650 batteries and a output of 2amps since the HDD wall wart is 12v 1.5amps.
