An SSD? I would recommend a A-data Premier Pro SP600, they are the cheapest and most reliable on the market right now. The 128 gb version is about $48, and 256 GB is around $85. Also, for the optical drive, LG drives are my favorite. Here's a cheap one. https://www.outletpc.com/ay6152-blk-g...20DVD%20Drives
Also, for the Optical drive, my friend can give you a windows 7 or 8 for around $5, if you would like.
On your monitor, are you looking for 4k, 1080p, 144hz, anything specific? Thanks and also leave a thanks if you liked it.
