Using Hot Swap Cage to "Extend" 5.25 Drive Bays?

[boat]

How practical would it be to use a hot swap cage commonly used in RAID setups with 5.25" drive bays as an extension to my case's limited number of drive bays?

 

I have a Thermaltake Core V31 - two 5.25" drive bays (should have picked a case with more drive bays, but too late), and the top is basically a big metal mesh board, designed to have the capacity to mount 3x 120 or 140 mm fans. I'm currently considering to do the following:

 

• Get one of these: http://www.newegg.ca/Product/Product.aspx?Item=N82E16816132037&nm_mc=OTC-sho6b0tCA&cm_mmc=OTC-sho6b0tCA-_-Server+-+Accessories-_-Rosewill-_-16132037 (woops, won't fit a DVD drive in there) http://www.amazon.com/SilverStone-CFP53B-Drive-Suspension-Mounting/dp/B0034XRDV4/ (should do the trick)
• Mount it to the top of my case (if it really doesn't work, I'll just have it sit on my desk like an external enclosure)
• The 2 drive bays in my case: LED controller, fan controller
• The 3 drive bays on the hot-swap cage: DVD-RW, BR-RW, Card Reader
• Sleeve the cables to blend in with the case, then run it into my case through one of the two cable holes in the back

Does this seem practical, or is there actually an item out there for this purpose?

Wouldn't something like this - http://www.amazon.com/Mediasonic-ProBox-HF2-SU3S2-Drive-Enclosure/dp/B003X26VV4/ref=sr_1_5?s=electronics&ie=UTF8&qid=1427451546&sr=1-5&keywords=external+hdd+enclosure make better sense?

Looking for 5.25" enclosure.

 

I'm looking for something like triple of these, but USB isn't necessary: http://www.newegg.ca/Product/Product.aspx?Item=N82E16827993013

 

So far, http://www.amazon.com/SilverStone-CFP53B-Drive-Suspension-Mounting/dp/B0034XRDV4/ seems to do the trick, and I can probably mount it on top of my case. okay no it doesn't, just read the description. Thought it could fit three 5.25" devices, but it's actually 5.25" to 3.5"
