Good to see there's still a few people running old cases - I still run a CM201 myself. Best advice i can give you is to check check and check again heatsink dimensions. some of the latest, largest heatsinks won't fit. not sure on the dimensions of your 101, but AFAIK the enzotech ultra heatsink fits in my 201. might be a wise idea to check the dimensions of your graphics card and psu as well - some are a bit larger than they used to be.
just check your dimensions. motherboard fit = shouldn't be an issue.
