desktop performances

have any of you performed, or thought of performing with a desktop instead of a laptop?

-most laptops have 13-14.5 inch screens, thats too small!
-most laptops have 250 GB hard drives @ 5400rpm, thats too slow and too small!
-most laptops have single or dual core processors running about 2.0gHz, too slow!
-most laptops have 3GB of ram, thats too little!
-most laptops have battery life of about two and a half hours, thats too short!
-most laptops with these specs cost around 650 USD, thats too much!
-most laptops have only 3 USB ports, i need more!

now, lets take a desktop package around 500 USD and compare it.

-21 inch HD monitor
-1 Terabyte hard drive
-quad core processor each @ 2.6gHz
-9GB ram
-infinite battery life
-500 USD
-6+ USB powered USB ports

..so what, if a desktop is LOL lbs.. ITS BEAST AMIRITE?!

Many people have built a PC inside flight cases, most have small screens plugged in to them, but I have put a full size screen in mine. If you are technical in any way, do your research and build one yourself.

PS, That's a 400w amp in there too (the small red thing in the 2nd photo). The whole unit is lighter than when you would put a turntable in the case and it is fully upgradable, so if any parts go faulty you can replace them with ease.

There is still a cover, fans and a few other bits to add on to this, but it works.

My main playing rig is a good old pc, even when i jump on the laptp i still use the 19" monitor. The eyes aint as good as they used to be
