Yes, the Begal Board Black (BBB) has much lower general CPU performance compared to the Raspberry Pibut MUCH better IO performance especially with those on-chip PRUs.
But still if you have a garage to store the computer and AC mains available for power why care about a few cubic inches and 20 watts of power? Gene suggested an Intel Atom based PC. Those work. But I find that one can buy Dell server that has come off lease. These can come in 1U size chassis which is very compact. Prices are very low and you get a full computer with power, chassis and so on. Smaller than a tower but still typically space for a PCIe card. Newegg.com is a reliable source, a top their retailer but eBay might have lower prices. I've seen a usable rack mount server go for $100. My main development PC is a used HP workstation, 12-core Xeon, 64GB RAM Nvidia GPU for about $550. The leasing companies have thousand of these and they have to dump them into a market where world wide PC sales is declining year to year.
