The real benchmark should be if it can explain Microsoft licensing without self destructing.

It was called Windows SideShow I think. I’ve been eyeing an XPS 420 because I’ve never had a system with one before.

Like the other commenters said, the performance per watt isn’t great but if your power is cheap, that won’t matter. You should be able to get quad core Xeon chips on eBay for super cheap (I bought a pair of E5440s for $16 I think). You got plenty of RAM already for a server of that era. Does it have a PCIe power plug inside? You’ll need that for those two GPUs.

So long it has PCIe, those cards are going to be backwards compatible with it. Whether you’ll be able to get their full potential performance depends on the rest of the system. That’s a mid to late 2000s server. What are the other specifications of it?

There is a guy who goes by “Cy” who posts videos online of homes he inspects in Arizona. There’s been some crazy stuff he’s found. I enjoy watching his content.

Cryptomator might be a good option. They have clients for Windows, macOS, and Linux. It’s designed around encrypting your cloud storage but nothing should stop you from using it on a USB drive.

Considering how many data breaches have happened this year alone, I wouldn’t be very surprised if your phone number was leaked in one of them, along with your email address. Make sure you use unique passwords for all your online accounts (a password manager can help with this).

IIRC in recent years eBay made it so that if you are one of their “top rated” sellers, buyers can’t leave the neutral or negative feedback for a week. Which is nice and all for sellers that are trying to resolve any issues a buyer may have, but not nice for situations like this one.
