I used to think highly specced cheap hardware deals were the best thing on earth until I got used to the electricity bills. Cheaper in the long run these days to build something modern that can chew less idle minimum power.
(personally having roaring servers would activate my ptsd from pulling floor tiles in a dark data center that is 15c at 3am)
but yeah the noise and power when you can get a tiny modern nas for not much money that sips power and is near silent and has more space and is probably faster than sas now as well (nvme slots). yeah I kinda get it? but not really.
A little bit of time and patience on eBay and you'll find all that most servers are vastly overpriced for what can be purchased, looks like you got a good value server, my latest addition is a VRTX complete minus disks for £500
used SAS drives on eBay are also pretty cheap. I picked up 4 6TB SAS drives for like $40US/each a few years ago. I just now have one starting to fail but it as 2400+ hours on it. Oh well.
Bloody bargain, well done mate, I'm quite jealous after spending a fortune on lots of new kit when I probably should've looked more at older stuff like this.
I have the T420. I really like it. It's quiet and just freaking works. Parts are easy to get. I bought the caster set off eBay so I can push it around and it gets it off the floor a bit. It's a heavy beast.
