@nyteschayde:
Two tips that should solve most of your space issues.
- Get a large (capacity) enough harddrive so you only need one harddrive.
- If you have a cd, replace it with a new short one (most new ones are just 17cm deep, but check the model you are considering before buying).
Btw, those flash-adapters should fit fine in the 3.5" slot under the diskdrive if you have an A4000 with a normal sized diskdrive - in other words not like mine which has an A2000 sized diskdrive. If you too would have such one, only slim 3.5" units will fit unless you replace the diskdrive or do some metalwork on the first unit you posted, as in that case only the front is the issue.
