Rackmounted gear is fine depending on where it is "racked" - some climates can get it into a garage, basement, etc.
But unless you have a real rack it's gonna be a bit of a pain, because it WILL end up being stacked on other pieces of gear in a rackish tower that requires full dismantling to get to the piece you want to work on.
If you go off-lease rack equipment, go whole hog and get a rack and rails too. Rails can be a bit pricey, check the listings for those that include them - rails often work for much longer than the servers so the big companies that liquidate off-lease equipment don't include them; smaller sellers often do.
