The 270 is a **** shell type case. On the top is a sort of dog bone gray piece, at the end is a black oblong, push down on this while gently pulling the back of the computer apart. There is another of these black oblong releases on the bottom. you need to do both. It will open up like a book, sorta cool once you get it open.

Re: open the tower?
There has to be a way to open the tower. Can you tell us the manufacturer of the PC you are referring to? If there's not the standard screws on the back of the case to take off the side, there must be a release button to pull the tower up, or something to that effect.

This sounds as if your video card is not seated. Your vidoe card is where the monitor connect to the tower. If you can open the tower locate the video card and check to see that it is seated in the slot firmly. Mkae sure to diconnect the power supply before opening the tower.
Can you please specify what model is your device.
Usually its the same as with tower type cases, its just that tower are stand in vertically.
You need to purchase Add-on PCI card for USB, and you also need to check if your computer has PCI slot for the add-on card.
Hi! it means that the monitor is not picking any signal from the tower or computer.Check all physical cables first esp the video cable from the monitor to the tower.Check if the computer has power by checking lights, sound coming of the machine. Check if monitor cable is securely plugged in to the vga or hdmi port.If you are using a adapter for that cable try to directly plugin the cable without using the adapter.If still no signal, check if you have a external video card or internal.if you have a external video card and thats the one that youre using then remove the external video card(you need to open up the tower and physically remove the external video card) and connect the video cable to the onboard card then check if will get a signal.hope this helps...
Are you sure there is no onbaord sound it should look like microphone or headphone socket holes. If it does then you are needing the correct driver. Open the tower and check what motherboard you ahve then post again for the correct driver.
If there is no sound onboard then it is very simple to install a pci soundcard anf they are very cheap. I certainly wouldn't go buying a new tower for just sound. Google on installing a pci card and you will see how easy it actually is or ask a young friend they know heaps about computers.
buy a sound card that you like and buy it. all sound card are PCI connections with PCI-E connections models are diffient. But your pc has pci connection. open up your pc and install the card. Listen to your music or play games.
