Sure...my bro uses as second screen an like 9years old SCOTT CRT, 19"...still keep working :)
But CRT's are awful for me...didnt have the free space for ;)
OhMyGod!!!!!!!!!!!!!!!!!
The CRT's are looking so badly massive vs. the small LCD ^^
but nice setup ;)
PS: You should get some LCD's instead of those CRT's!
