LackRack is cute in that it works and fits, but the real home datacenter is wire shelving - one of THOSE bad boys can support hundreds of pounds AND have good airflow (and sneaky cable routing!).
If you trawl auction sites for business liquidations, you can also usually pick up an actual rack for pennies on the dollar.
It doesn't even have to be a tech business; most random offices have a small rack in a closet somewhere with some networking equipment on it, and the whole thing usually sells as one lot to anyone with $50 and a screwdriver to remove the equipment from the site.
They're not hard to find as you say (you can even find them at scrap yards and such) - though then you can find the fun of getting the right mounting hardware to actually PUT things in the rack (and you get to learn the difference between telco racks (very common) and server racks (somewhat less common).
If you've accidentally purchased a telco rack it won't be ideal, but modifying it into a server rack is going to yield a better rack than a coffee table or bookshelf.
Yeah for a lot of things these days I actually prefer a telco rack, as you’re unlikely to be shelving giant rack mount chassis and UPS as much as you used to.
