If planning to put a high performance Video card like a GTX 260 which is the one that i got, be prepared to modify the cover on the videocard or you have to get an extension for the motherboard plug. Try to get a 9.5 video card like an Radeon HD 4870.

This product is really great. My processor and ram including video card and HDD were recognized without a problem. Cable routing and cleanness of the case inside was really neat as well. PS is great and can handle high end graphics card. Very satisfied

Excellent Design


After much experimentation, I ended up with EVGA 512-P3-N973-TR GeForce 9800 GT and the EVGA 256-P2-N429-LR GeForce 7200GS.

Typical Shuttle -- quality design and construction

Hard to fit two quiet video cards with one that has decent game performance. I need two cards to support three monitors for regular/work use. I really wanted to go passively cooled but there's no way to do that with this case because all the performant...

Excellent daily use head for hardwood floors!


I bought this head thinking I would use it under beds and furniture, but I have found that it works so incredible on my hardwood, tile and low pile carpets that I use it as my primary head. The low profile is awesome to fit under cabinets. etc...not...

Great addition to my vacuum.


This tool does not do to well on the carpet. But for the hard floors it is amazing.

Consumer review by:

Not too bad


It really did a great job getting udner the bed, dresser, etc. I do wish there was some way to get agitator brushes on the piece but I guess not.

Works great, but wand is weak link


Great power for a small cleaner. Easy to dump waste.

Poor wand design prone to breakage, terrible parts replacement service.

Dyson DC08 Cylinder Bagless Canister Cyclonic Vacuum


Great suction, brilliant design, and NO BAG!

Small dirt bin, a bit bulky.
