That rim should work. It's probably a shitty-ish rim, but would work for what you're trying to do-no show piece for sure.
Just remember if the spokes are a tad long-they can be shortened beforehand, or you could grind them flush once you assemble the wheel, if that is how you go about it-just take your time, and as cheap as that rim may be-just before you put the rim strip over the nipples, rub some grease aroudn that lower portion of the rim, it'll help to keep it from rusting so bad overtime. just my .02
