it doesnt matter what processor u have, in indian climate everything gets burn. so buy a table which hasnt got closed box for ur cabinet. if u dont have enough space then go for smaller pc tables but let me warn u that u wont b getting any space for ur printer/scanner etc. i have a bigger pc table and its perfect. on top, i have my monitor, speakers, phone, mouse, printer. make sure the keyboard slot in the table has slider. u know the one which goes in and out
one more thing, whatever u buy, pay close attention to the chair, if u choose wrong chair then u will b suffering from back pain for the rest of ur life
