Among other things, I have to take a desktop computer - specifically a Dell Inspiron - on a trip.

Does anyone have experience knowing if it will fit in a standard-sized rollerboard? (The computer and the rollerboard aren't in the same city right now, need to decide if I need to take the rollerboard for it.) Advice for packing it other than lots of bubble wrap?

Unfortunately, I discarded the original box it came in, or I would check it.

If you put a "fragile" tag on a checked bag, will they actually not throw it around?

Sidebar, many years ago (close to 20) I checked a bag and for some reason they asked me what was in it and I said "Hardware" and they made me sign a damage release. The hammer, wrenches, and fasteners made it to the destination unharmed!
