Metal case for computer

[francisjkearney]

Hi,

I would like to replace the metal case of my computer. I replaced my system cooler with a new one and is not compatible with the old case. I would also like to add more internal storage drives and so I would require a custom made case like these, http://www.bayviewmetals.com/rack-mount.php .Could anyone have tried buying them online? Or have you tried DYI, http://www.instructables.com/id/How-to-DIY-Modded-Computer-Case/ ???

Thanks in advance!
