New build for an old operating system

I want o build a new system that will run DOS 6.22 and maybe Windows 95.
The reason is I want to be able to run some old games I have without having
to use any sort of emulation.

My question is will DOS be able to run on an Intel Celeron using DDR memory?
Has anyone recently build a machine for this purpose?

I guess you are right everything should be backwards compatible.

Not all MB chip sets support DOS. I believe the change for nvidia came with nforce 3 that did not support Win98 (DOS kernel) and older, only XP (NT OS2 kernel). I suppose the biggest problem would be driver support.

You need an old $50 computer. I wouldn't build.
Windows 95 only requires like 64mb Ram.

If you want to build, I would dual boot.

For a long time, I played civilization-2. The requirements were dos 5.0 or higher, or windows 95. I kept installing this on every new os including vista 32 bit, where it ran without a problem. I got stopped when I went to vista-64. The reason was no support for 16 bit programs.

The net of this is that I think your games should run on any modern windows machine natively, just so long as it is a 32 bit os. Can you test this out somewhere?

Thank you all for pointing out the possible problems that might come up.
I think driver problems will be the biggest since I just want to use a motherboard with integrated graphics and sound. As for memory management I think something will come up from 20 years ago if I stare at the screen long enough.

I've got at least 3 PI boxes buried out in garage that all have 95 on them.
