Looks like an IBM PC (5150), actually. If that's the case, it comes with somewhere between 64 and 640 kB RAM (depends on how many chips are populated on the board, and whether or not an expansion board has been fitted), with zero to two 160, 180 or 360 kB Tandon 5¼" floppies and a tape interface in the back (that's the defining difference).
And BASIC in ROM. It fires up by default if the floppy controller isn't present, but there was a small MS/PC-DOS program to jump to the BASIC ROM after boot, if you felt like it.
I have one in the room with me right now, complete with the tape interface. It still works.
By the way, the EGA didn't come out until the IBM AT (the 80286 one). The PC and XT came with an IBM MDA (80×25 @ 8×16, monochrome text only, quite crisp for the time). The CGA was a later upgrade (320×200 with 4 colours, 640×200 with 2 colours, and not very legible 8×8-cell 80×25 and 40×25 16-colour text modes — the latter used for TV output with an optional RF modulator).
