It doesn't really matter. Having the two drives installed will increase the load on the power supply slightly. When I installed the burner in mine I left the DVD reader installed just so I could be lazy when copying disks.
I'd leave it in. The downside of doing so is negligible, and it's sometimes useful to have two drives in the box.tapehoser said:This is an 'everything' drive. It can play CD's, burn CD's, play DVD's, and burn DVD's. Even the multi-layered DVD's that hold 8-9 Gigabytes.
