Well, for one thing, that site you referenced, hashrates.com, is focusing on XMR/Monero instead of Raptoreum. But, fundamentally, Raptoreum is essentially near valueless. You'd do better just investing spare pocket change that you find in your sofa to buy it instead of mining it because of how much electricity it will cost you to do so. XRM has a lot more value (over $100 a coin vs. raptoreum at less than a cent). You can possibly make money on mining XMR/Monero with your CPU if you have very cheap electricity, but you have to exclude the purchase price of the equipment that you buy.
Long term, Raptoreum peaked in value at the end of 2021 and has basically tanked and flat lined since then. XMR/Monaro followed the general coin market, but has retained some value and has, of recent, been trending slightly higher. If I was you, and I absolutely had to coin mine, I wouldn't go the big chunky server route. I'd be buying the now bargain priced 5600 processors from AMD, the cheapest A300/500 board that you can find to run them, a tiny, efficient power supply, the cheapest video card that you can find to put up a picture and let it boot, and the cheapest possible tiny case you can fit it all in and start mining xmr with that. Just understand that you're just throwing your money away right now. You won't mine more value than the cost of your electricity.
But, in your case, if it was me, I wouldn't mine. I'd be finding a fiduciary, set up an investment plan to invest whatever extra money you have coming in, and try to build up a degree of passive investment income. Interest rates make the bond market at least somewhat interesting (though, yields are a basket case right now). Safer REITs are also a decent place to start. But, I'm just some guy on the internet, so find a fiduciary that can handle getting you started.
