No, I think it would probably be best to buy a new computer that can run these games in DOSBox at full speed. While there is a lot of fun involved in tweaking obsolete hardware and software for those so inclined, I get the idea that you're mainly just looking to play the games. You could get lucky and find an ancient box for cheap or even free, but old hardware takes up space, is noisy, can be quirky or partially dysfunctional due to old age, and is in any case much, much, more difficult to set up than DOSBox.
You'd be going through a number of things that you may not be familiar with. BIOS settings, which won't save if the onboard battery is depleted. Hard drive partitioning, and to be careful there because either DOS or BIOS may be picky about what kinds of geometry it supports. Installing the system from floppies or cd, some of which, or the drive for, will be broken or working poorly. Optimizing your memory configuration with autoexec.bat and config.sys to conserve as much of the precious 640k base memory as you can. Figuring out how you're going to transfer data from your main PC to the old one. And when you're you're finally done you'll discover that the hard disk was being extra noisy because it was about to give up the ghost and just did.
