My old no-name small form computer almost caught fire in it's always troublesome power supply, so it was time to buy a new (to me) computer. Went down to EPC Computers (https://www.epcusa.com/computer-sales/ ) and got the smallest form computer they had, a Lenovo Thinkcentre M92P Tiny-- most of EPC's used computers have manufacture date on their i.d. sticker, but not this one. Figure it's about seven years old. The sticker said Win 7 but they had Win 10 on it. I tried to get a bare computer but that would have involved shipping one from Las Vegas at a cost of about $20 and I didn't want to wait. Hate paying $50 for Windows that I had no use for, but for a price of $195 out the door, the extra fifty won't break me.
Almost kept Win10 on the computer long enough to play with it-- never used Win 8 or 10, but then I couldn't say that I haven't used Windows in years, so it died an instant death. Has an Intel Core i5i5 with 8 eight gig of memory and a 64 gig SSD. I suspect this would be underpowered with Win 10, but with a lightweight OS like Mate 18.04, this thing literally screams. About twice the processor, twice the memory and more than twice the power of my (offbrand) SSD in my old computer. EPC does nothing but commercial computers off lease and this thing is built like a proverbial brick outhouse.
Here's a review of the same basic thing, but with less power: https://www.anandtech.com/show/6162/lenovo-thinkcentre-m92-system-review-pintsized-power
Didn't mean to be a Lenovo fan boy but I now have their computer, Chromebook, and E4+ phone. I'm still brand agnostic other than maybe Moto phones, purchase decisions just happened this way. We'll see if they're put out of business on tariffs or spying.
After a week, I'm in love with this little powerhouse-- at least compared to what I'm used to-- it screams. Like having that eight gigs of memory. I absolutely love Ubuntu Mate. It replaced Linux Mint and Peppermint Linux about six months ago as my only operating system.
